add support for alternative C libraries (currently only glibc/eglibc) other (related) changes: - kernel headers are now installed using "make headers_install" on 2.6 - target names now contain an openwrt "vendor" tag (e.g. mips-openwrt-linux-gnu) - build directory names now contain gcc/libc name/version - default cpu for x86 is now i486 (required to build glibc/eglibc)

+       With this option group enabled, all EGLIBC functions for
+       accessing various system databases (passwords and groups;
+       networking; aliases; public keys; and so on) consult the
+       '/etc/nsswitch.conf' configuration file to decide how to handle
+       queries.
+
+       With this option group disabled, EGLIBC uses a fixed list of
+       services to satisfy queries on each database, as requested by
+       configuration files specified when EGLIBC is built.  Your
+       'option-groups.config' file must set the following two
+       variables:
+
+       EGLIBC_NSSWITCH_FIXED_CONFIG
+
+          Set this to the name of a file whose contents observe the
+          same syntax as an ordinary '/etc/nsswitch.conf' file.  The
+          EGLIBC build process parses this file just as EGLIBC would
+          at run time if EGLIBC_NSSWITCH were enabled, and
+          produces a C library that uses the nsswitch service
+          libraries to search for database entries as this file
+          specifies, instead of consulting '/etc/nsswitch.conf' at run
+          time.
+
+          This should be an absolute filename.  The EGLIBC build
+          process may use it from several different working
+          directories.  It may include references to Makefile
+          variables like 'common-objpfx' (the top of the build tree,
+          with a trailing slash), or '..' (the top of the source tree,
+          with a trailing slash).
+
+          The EGLIBC source tree includes a sample configuration file
+          named 'nss/fixed-nsswitch.conf'; for simple configurations,
+          you will probably want to delete references to databases not
+          needed on your system.
+
+       EGLIBC_NSSWITCH_FIXED_FUNCTIONS
+
+          The EGLIBC build process uses this file to decide which
+          functions to make available from which service libraries.
+          The file 'nss/fixed-nsswitch.functions' serves as a sample
+          configuration file for this setting, and explains its syntax
+          and meaning in more detail.
+
+          This should be an absolute file name.  The EGLIBC build
+          process may use it from several different working
+          directories.  It may include references to Makefile
+          variables like 'common-objpfx' (the top of the build tree,
+          with a trailing slash), or '..' (the top of the source tree,
+          with a trailing slash).
+
+          Be sure to mention each function in each service you wish to
+          use.  If you do not mention a service's function here, the
+          EGLIBC database access functions will not find it, even if
+          it is listed in the EGLIBC_NSSWITCH_FIXED_CONFIG
+          file.
+
+       In this arrangement, EGLIBC will not use the 'dlopen' and
+       'dlsym' functions to find database access functions.  Instead,
+       libc hard-codes references to the service libraries' database
+       access functions.  You must explicitly link your program
+       against the name service libraries (those whose names start
+       with 'libnss_', in the sysroot's '/lib' directory) whose
+       functions you intend to use.  This arrangement helps

+                    
+        Note that the GNU standard C++ library, 'libstdc++.so', uses
+        some of these functions; you will not be able to link or run
+        C++ programs if you disable this option group.
+
+        This option group also affects the behavior of the following
+        functions:
+

+          fopen
+          fopen64
+          freopen
+          freopen64
+
+        These functions all take an OPENTYPE parameter which may
+        contain a string of the form ",ccs=CHARSET", indicating that
+        the underlying file uses the character set named CHARSET.
+        This produces a wide-oriented stream, which is only useful
+        when the functions included in this option group are present.
+        If the user attempts to open a file specifying a character set
+        in the OPENTYPE parameter, and EGLIBC was built with this
+        option group disabled, the function returns NULL, and sets
+        errno to EINVAL.

+Fixes a MIPS build problem (unrelated to NPTL)
+
+Message-ID: <428E8B24.1000201@realitydiluted.com>
+Date: Fri, 20 May 2005 20:13:08 -0500
+From: "Steven J dot  Hill" <sjhill at realitydiluted dot com>
+To:  crossgcc at sources dot redhat dot com,  toolchain at gentoo dot org, 
+ Shay_Gal-On at pmc-sierra dot com,  TheNop at gmx dot net
+Subject: New NPTL patches for crosstools and MIPS NPTL patches....
+
+Greetings.
+
+I have uploaded the latest NPTL patch for crosstool-0.34. I have also
+uploaded a tarball of the patches necessary to build a MIPS NPTL
+cross toolchain. To build a MIPS NPTL toolchain you will need the
+released version of binutils-2.16 and the absolute latest GCC and
+glibc code from the HEAD of cvs. Use the 'demo-mips-nptl.sh' script
+to build the toolchain. Please report bugs or issues to the crossgcc
+mailing list. Here is the link off of my FTP site:
+
+    ftp://ftp.realitydiluted.com/crosstools/crosstool-0.34/
+
+[Note: BOOTSTRAP_GCC is set by crosstool.sh when invoking make install-headers]
