Make checking the linux installed headers optional (instead of systematic).

28 I believe this flushes my current patches to make glibc work on SH. Issues:
29 - MIPS pread functions have some wackiness in them for the MIPS calling
30 conventions, which align long longs to even register pairs; it appears
31 that SH does not do this. This fixes pread64/pwrite64.
32 - st_ino is _NOT_ 64-bit in the latest SH kernel trees, or at least it
33 wasn't when I checked in April. --enable-kernel=2.4.x breaks terribly
34 without this patch; the errors are along the lines of "version GLIBC_2.3
35 not found", because that's the first consequence of a messed up inode
36 field - ld.so compares by inodes at some point.

44 * sysdeps/unix/sysv/linux/kernel-features.h: Update kernel features
45 for the SH architecture.
46 * sysdeps/unix/sysv/linux/sh/pread.c: Use generic Linux version
47 instead of the MIPS version.
48 * sysdeps/unix/sysv/linux/sh/pread64.c: Likewise.
49 * sysdeps/unix/sysv/linux/sh/pwrite.c: Likewise.
50 * sysdeps/unix/sysv/linux/sh/pwrite64.c: Likewise.
