configure uses uname -m to make assumptions about what code gcc will
generate. But this kind of guessing does not work on ppc and sparc because
the gcc defaults to 32bit output.
Either use 'powerpc32 ./configure ...' to fool configure and build a
32bit glibc.
Or use 'CC='gcc -m64 ./configure ...' to tell gcc to generate 64bit
code. You will need some of the -devel-64bit.rpm packages for 64bit
libraries.
