Since Geoff is worried about future binary compatibility apparently, it
would probably be easier to modify gnatlink.adb to emit -static-libgcc or
-shared-libgcc depending on whether static or shared gnatlib is used.
The problem is that passing -static-libgcc unconditionally can theoritically
cause problems on Linux when C code using POSIX threads is linked. So we
would need to do that only on Darwin.
Then set a var in link.c for darwin and use that as the conditional?

You'd have to add the idiocy flag elsewhere too and default to 0.
