This is most likely due to a relocation error. Compile uClibc
with debug support enabled and run your program with the
LD_DEBUG environment variable set. If there is proper debug
support in the ppc ld.so that should give you some clues to what
is happening.

Also; try running the program with LD_BIND_NOW=1, if that works
there's some fishy things happening with lazy relocations.
