Ok, my applications runs if its dynamically linked, but if I debug it
using gdb-5.3/gdbserver I get the following:

(gdb) set solib-absolute-prefix /dev/null
(gdb) set solib-search-path /usr/local/wave/x-ppc-linux2/powerpc-linux/lib
(gdb) tar remo 10.1.1.3:3001

And gdb never comes back to me(whether I us step, stepi, continue, and
it is interruptable with a C-c, but the pc is still at 0xfdd4d5c).

Any suggestions as to why its not executing under gdb are highly appreciated!
