Merge tag 'kbuild-v4.17-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull more Kbuild updates from Masahiro Yamada: - pass HOSTLDFLAGS when compiling single .c host programs - build genksyms lexer and parser files instead of using shipped versions - rename *-asn1.[ch] to *.asn1.[ch] for suffix consistency - let the top .gitignore globally ignore artifacts generated by flex, bison, and asn1_compiler - let the top Makefile globally clean artifacts generated by flex, bison, and asn1_compiler - use safer .SECONDARY marker instead of .PRECIOUS to prevent intermediate files from being removed - support -fmacro-prefix-map option to make __FILE__ a relative path - fix # escaping to prepare for the future GNU Make release - clean up deb-pkg by using debian tools instead of handrolled source/changes generation - improve rpm-pkg portability by supporting kernel-install as a fallback of new-kernel-pkg - extend Kconfig listnewconfig target to provide more information * tag 'kbuild-v4.17-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: kconfig: extend output of 'listnewconfig' kbuild: rpm-pkg: use kernel-install as a fallback for new-kernel-pkg Kbuild: fix # escaping in .cmd files for future Make kbuild: deb-pkg: split generating packaging and build kbuild: use -fmacro-prefix-map to make __FILE__ a relative path kbuild: mark $(targets) as .SECONDARY and remove .PRECIOUS markers kbuild: rename *-asn1.[ch] to *.asn1.[ch] kbuild: clean up *-asn1.[ch] patterns from top-level Makefile .gitignore: move *-asn1.[ch] patterns to the top-level .gitignore kbuild: add %.dtb.S and %.dtb to 'targets' automatically kbuild: add %.lex.c and %.tab.[ch] to 'targets' automatically genksyms: generate lexer and parser during build instead of shipping kbuild: clean up *.lex.c and *.tab.[ch] patterns from top-level Makefile .gitignore: move *.lex.c *.tab.[ch] patterns to the top-level .gitignore kbuild: use HOSTLDFLAGS for single .c executables
