glibc-2.1.3, asm/elf.h and PPC kernels with AltiVec support

[Franz Sirl]

Hi,

current glibc-2-1-branch breaks on the latest 2.2 kernels containing 
AltiVec support:

make[2]: Entering directory
'/usr/src/redhat/BUILD/glibc-2.1/linuxthreads'

I think the correct fix would be a separate sys/elf.h for PPC, like what 
x86 and arm already do.

If there are no objections, I'll put together such a file and post it later 
today with the corresponding changes to other files.

Franz.
