Are you using uClibc from CVS?  There a few known problems with
building non-uClibc shared libraries with the release, since there
was a stray R_PPC_REL24 reloc in crt0.o.  Uclibc's ld.so now
enforces that shared libs have no improper relocations on ppc.

Otherwise, you can check that ld.so is really the problem by
substituting glibc's ld.so.  If it is a problem, there's a
#define somewhere to enable debugging output in ld.so.
