What's the purpose of the `--enable-ld` option of `configure`?

Another place to look is the crosstool-ng source.
http://crosstool-ng.org/hg/crosstool-ng/file/7fe58a4f79f8/scripts/build/bin
utils/binutils.sh#l150

They don't seem to use enable-ld with gcc, just with binutils. If we built
binutils with gold, we still need to tell gcc to use gold or ld (default).

gcc.sh#l751

Hope that helps.
