It seems the linker flags are somewhat different on OS X.
"-whole-archive" is supposed to be replaced with "-all_load", but I
can't seem to find a replacement for "-no-whole-archive".  The
replacement was *supposed* to be "-noall_load", but that seems to be
deprecated and ignored.

I'll keep researching on OS X, but build on linux for now.  Thanks for
the pointers!
