Comment:
i've reworked and built every crosstoolchain (some on multiple hosts)

also, it's no longer required to specify the component versions via `cross_*_version`; the build-style magic guesses it automatically

same also applies to `cross_libc` and `cross_wordsize`, both are guessed automatically without any intervention (the former is based on existence of directories, the latter is dug up from the initial bootstrap gcc for the target)
