Caught this headache while trying to bump to Ubuntu 22.04, which required touching way too many surprising places.
Current GHA scripts define `apt-gcc-version` a bit weirdly: host and cross builds version differ in carrying the "gcc-major-version" inside of it. That is, "host" builds do `apt-gcc-version: '10=10.3.0-1ubuntu1~20.04'`, while cross builds do `apt-gcc-version: default: '10.3.0-1ubuntu1~20.04'` I propose we harmonize these to simplify GCC updates: split out the `gcc-major-version` for host builds, and pull the versions from cross builds into `main`, where all other versions belong. Additionally, this handles the x86_32 case that requires "-multilib" package, which is currently hacked through the "version" string.
