description:
llvm: On NetBSD/powerpc 8.x or 9.x, omit use of -mno-pltseq.

Fixes build on NetBSD/macppc 8.0, where we end up with pkgsrc gcc7.
NetBSD 9.0 has gcc 7.4 in-tree, so is also missing -mno-pltseq.
On non-NetBSD powerpc platforms, for now just insist on -mno-pltseq,
i.e. a gcc at least newer than 7 (untested).
