More candidates for toolchains on linux

• gnu.org/autoconf
• gnu.org/automake
• gnu.org/libtool
• (possibly) perl.org

lots of tools (cough configure cough) expect some or all of these as a matter of course. the most recent yarnpkg.com build failure was buried in a log where the mozjpeg module was trying to recompile its binary bits.

obvious downside is masking a runtime dependency (mostly only in the case of perl.

note that unless explicitly adding pkg-config, automake doesn't seem to be able to find pkg.m4.

the tests don’t get the toolchain so thorough tests should be enough

[jhheider]

it's a great point.

ah yes. This would indeed be the danger of shims. We could have brewkit always add pkg-config to the env. Dunno. Let's decide next time a build error like that happens.

that's a deep cut, certainly. i expect that to be rarely found.
