dev-libs/ntl: new version 11.4.3.
Update to the latest version using François Bissey's ebuild from the
sage-on-gentoo overlay. I've updated the LICENSE to LGPL-2.1+ per the
project's homepage, and have removed the CFLAGS override since now
NTL builds and passes its test suite with -O3 (if you set anything
higher than that, you're on your own). I've also tried to simplify
a few of the usex calls in the DoConfig process.
