Don't use INTDEF for powerpc32 compat symbols (bug 14132).

Continuing the removal of the obsolete INTDEF / INTUSE mechanism, this
patch removes the use of INTUSE to rename symbols in
sysdeps/powerpc/powerpc32/libgcc-compat.S.  As the names in question
are purely internal to this particular object and not used anywhere
else, it doesn't matter at all whether __*_v_glibc20 or __*_internal
is used, so this patch just removes the macros in question.

Tested for powerpc32 that stripped installed shared libraries are
unchanged by this patch.
