Those are (I think) just a commented list of "things you might add when
doing a port of your own".  I could be wrong.

Maybe try --enable-cxx-flags='-ffunction-sections -fdata-sections' too.

Definitely.  I'm working on this as my schedule and wrists allow.

Absolutely.  All the --enable/--disable/--with/--without configure flags
are passed to all the sub-configures for exactly this reason; any flags
not understood by a particular configure script are ignored.
