Add (implicit) support for musl libc
This is mostly achieved by fixing or refining the inclusion of header
files and replacing glibc-specific ifdefs with more generic ones.
- <sys/io.h>: Contains iopl(2) and x86 I/O port access functions (inb, outb etc).
Generally Linux-specific but also availble on debian/kFreeBSD.
Provided by glibc as well as musl and uclibc.
Include it if we are running Linux or if glibc is detected.
- <sys/fcntl.h>: should be (and is) replaced by <fcntl.h> (without the
"sys" prefix).
- <linux/spi/spidev.h>: Does not include all necessary headers, namely
_IOC_SIZEBITS that is used in the definition of
SPI_MSGSIZE is not brought in via <linux/ioctl.h>
but instead we relied so far on glibc's including
it via <sys/ioctl.h>. Change that to explicitly
including <linux/ioctl.h>.
- <endian.h>: Would also be available in musl but there is no easy way
to detect it so we do not try yet.
Corresponding to flashrom svn r1898.
