The same situation that effected ARM effects PPC with regards to placing the

LSDA into the TEXT section. We need to generate non-lazy pointers to it on
Mach-O. However, the object the NLP points to may be local to the translation
unit. If so, then the NLP needs to have the value of that object specified
instead of "0", which the linker interprets as "external".
