gcc-config: set CCACHE_COMPILERCHECK to major GCC version
This avoids invalidating caches on every GCC snapshot bump for the same
major version (e.g. 12.2.1_p*), but also for 12.1 -> 12.2. It should be fine
to mix objects between such versions.
If needed, we can swap this to just stripping .1_p* but that's a bit
more awkward.
