Ah.  I've now hit that as well.  It seems kind of bogus that darwin is
versioning getopt, but not the opt* variables that it uses.

To avoid the problem with libiberty and mdsetimage, the only way I could
find was to include unistd.h in the getopt.c in libiberty so that the
version of getopt in libiberty also got the rename.
