Re: Yacc Shaving, or, Latest macOS CLT Laccs Something

More macOS Command Line Tools 15.3.0.0.1.1708646388 fallout!

With the previous workarounds committed, I ran another 
pkg_rolling-replace. It went pretty normally (yay), modulo a handful of 
packages failing at invocations of flex(1).

The problem, revealed by TOOLS_ALWAYS_WRAP=yes: /usr/bin/flex was 
attempting to invoke /usr/bin/gm4, which is noted in tools.Darwin.mk as 
something to avoid.

Manually adding "gm4" to USE_TOOLS for each of my failing packages 
(gobject-introspection, MesaLib, netpbm, gstreamer1, lilypond) fixed 
their builds by letting pkgsrc control which gm4 gets found.

I'm now testing the following diff on my afflicted macOS and elsewhere:
