Trac #18424: FLINT 2.4.5's test suite fails unconditionally (t-NTL-interface)

FLINT 2.4.5 (and 2.4.4 at least) '''unconditionally''' fail its test
suite when building the NTL interface test due to a bug in the
`Makefile`:
{{{

sage-on-gentoo and now Gentoo proper have carried a patch for the issue
for some time now. See
