>Description:
The file exec_elf32.c currently doesn't know about the PowerPC ELF format,
for that reason a PowerPC buildworld currently fails with:

%%
cc -O -pipe  -c rescue.c
echo "int _crunched_cat_stub(int argc, char **argv, char **envp){return main(argc,argv,envp);}" >cat_stub.c
cc -O -pipe  -c cat_stub.c
ld -dc -r -o cat.lo cat_stub.o /freebsd/ppc-uchar/obj/powerpc/freebsd/ppc-uchar/src/rescue/rescue//freebsd/ppc-uchar/src/bin/cat/cat.o
crunchide -k _crunched_cat_stub cat.lo
cat.lo: unknown executable format
*** Error code 1
%%
	
>How-To-Repeat:
	
>Fix:
All that is needed is to add case EM_PPC to the switch.  For consistency with
the other "exotic" architectures EM_PPC is defined if it isn't already.
