Obsoletes the powerpc-unknown-linux-gnuspe sample, so remove it.

The following makes it possible to configure glibc-2.3.2 on Mac OS X,

where the assembler but doesn't understand the --version flag.

Fixes the symptom

checking whether ld is GNU ld... no

checking for /usr/libexec/gcc/darwin/ppc/as... /usr/libexec/gcc/darwin/ppc/as

checking version of /usr/libexec/gcc/darwin/ppc/as...
