[Gc] Re[2]: Build with -m32 on 64bits OSX

[Margaret Fleck]

I just compiled an old 32-bit code package under OSX (10.7.5).
I'm getting the same error messages about libgc.a not containing
any symbols, when I compile gc 7.2.   However, my code using
libgc.a seems to compile and run just fine.    So I suspect the
error messages are bogus.  E.g. maybe there is a mac-specific
issue with whatever routine is being called to try to check
whether libgc.a is ok?

I'm passing -arch i386 to CFLAGS but not to LDFLAGS, for the
record.
