ppc: Do not generate .stabs ELF sections to prevent GDB from choking on them
Recent versions of GDB (and probably older ones too, but not checked) crash
with and abort when loading the non-stripped 32-bit PPC QEMU build[1]. This
is due to a bug in GDB on reading stab symbols. The only place in OpenBIOS
where stab symbols are generated is in libgcc/crtsavres.S, which was copied
from the linux kernel[2].
Symbols that were defined in the stabs section are still able to be seen in
GDB after stabs removal. There does not appear to be a loss in debugging
functionality.
