Using ld directly is wrong because it fails to add implicit linker
options, in particular crt*.o. For example, on SCO, giving -Kpthread
to the compiler implies giving -lpthread -l<some funny library that
you cannot guess> to the linker.

Likewise, using gcc on Solaris, linking with gcc implies linking
crtbegin.o and crtend.o, which is necessary to run constructors of
global C++ objects. The same holds for SunPR, which implicitly links
crti.o, crt1.o, values-xa.o, and crtn.o for an executable, and crti.o,
values-xa.o, and crtn.o for a shared object.
