There are probably several problems in the details, but the main one
is that the target memory layout used by your linked powerpc program
does not match that simulated by psim ("target sim" in powerpc gdb).
Why did you use a custom linker script? Try building your program with
powerpc-eabi-gcc -msim FOO.c -o FOO.x
and running it with
powerpc-eabi-run FOO.x # to run under the stand-alone simulator
#or powerpc-eabi-gdb FOO.x # then "target sim", etc.
