[Darwin] Some TLC for older Darwin versions.
The library handling and some of the options for creating the crts for
the older PPC Darwin versions had bit-rotted somewhat. This adjusts the
build criteria for the crts to avoid newer ld64 versions warnings about
mismatches in build and object versions.
Added to some of the comments that it's documented why the specs are as
they are.
