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.
