Ok, first problem for x86 is Glibc-2.6 doesn't support i386 anymore. Lowest
supported config is apparently i486. We'll have to change the temptools
Glibc to compile with -march=i486 (chroot Glibc already uses -march=i686 so
it's sweet):

Second problem is coreutils-6.9 fails to compile. Glibc-2.6 has apparently
gained futimens() and it conflicts with the Coreutils version. I tried
hacking Coreutils to make it build but gave up after half an hour of
frustration. Instead, I just remmed out the futimens declaration in
sys/stat.h :-/ Someone needs to fix Coreutils.. I've sent upstream a note:

http://lists.gnu.org/archive/html/bug-coreutils/2007-05/msg00158.html

Glibc-2.6 tests for GCC-4.2 and adds `-fgnu89-inline' to CFLAGS which gets
rid of the earlier mentioned warnings.

There are still testsuite errors but slightly better than earlier:

# grep "\*\*\*.*Error" glibc-2.6.log
make[2]: *** [/temptools/src/glibc-build/math/test-double.out] Error 1
make[2]: *** [/temptools/src/glibc-build/math/test-ldouble.out] Error 1
make[2]: *** [/temptools/src/glibc-build/math/test-ildoubl.out] Error 1

make[2]: *** [/temptools/src/glibc-build/posix/tst-vfork3.out] Error 1
make[1]: *** [posix/tests] Error 2
make: *** [check] Error 2

More later...
