other/10901: non-local goto's (still) don't work on apple-powerpc-darwin

[Andrew Pinski]

This should be target, as it only effects powerpc-apple-darwin.

In 3.4 (do not know about 3.3):
It looks like the register that is holding the pic address is 
overwritten in bar so when the jump happens the pic register now holds 
the pic for bar, not for main so it prints out some garbage.
It looks like it should save and restore it in r30 like stack register 
is.
A workaround in 3.4 for applications is to use -mdynamic-no-pic which 
will get rid of the pic code.

Thanks,
Andrew Pinski
