I think you are using the wrong libgcc.a
It should probably by .../3.4.4/nof/libgcc.a or some such.

Humm! libgcc.a  is in the *_nofpu subfolder:

../build_arm_nofpu/staging_dir/lib/gcc/arm-linux-uclibc/3.4.4/libgcc.a

It seem to be a config problem ; 
it looks like a missing  file that should be linked to complete the
library. 
see nm command  result.

gcc 3.4.3 has it in 3.4.3/nof/libgcc.a for powerpc
