Linux improvements

[d.healey]

I've made a PR that combines a bunch of commits, you can read the full list of improvements on github.

Basically I added exporters for faust to the standalone project, fixed gcc >= 11 support, and almost fixed font loading (it's close enough).

I've tested this on Linux Mint 18, Debian Bullseye, Trixie, and Testing. Seems to work but it would be good to get more feedback in case I missed something.

Slight update. I've merged the configs from the faust and non-faust exporters into a single exporter - like it is for the other platforms.

For example, you can now use CONFIG=ReleaseWithFaust
