- remove devel/gflags BDEP, it uses an internal copy by default - add hidden dep on gmp/gmpxx and sync WANTLIB - garbage-collect CONFIGURE_ARGS, sort LIB_DEPENDS - drop -pthread CXXFLAGS spotted by brad - ONLY_FOR_ARCHS=amd64 (was previously amd64 i386); only supported upstream on 64-bit arches and a dep is BROKEN on i386 anyway so it wasn't built there. (perhaps aarch64 could be added though?)
