detect-compiler: make detection independent of locale

`detect-compiler` has accumulated a few compiler dependent workarounds
lately for the more and more ubiquitious gcc12. This is intended to make
CI set-ups work across tool-chain updates, but also help those
developers who build with `DEVELOPER=1`.

Alas, `detect-compiler` uses the locale dependent output of `$(CC) -v`
to parse for the version string, which fails unless it literally
contains ` version`.

Use `LANG=C $(CC) -v` instead to grep for stable output.
