[PATCH] Add sysdeps/x86/i686

[Roland McGrath]

What's the benefit of adding a new sysdeps directory?

For the common Makefile parts you could just move them into a
sysdeps/i386/i686/cacheinfo.mk and sysdeps/i386/i686/hp-timing.mk and
then include those from both sysdeps/.../Makefile files.

For the source files what sysdeps/x86_64/hp-timing.h already does
is better than #ifdef's in the shared file.


Thanks,
Roland
