Subject: [PATCH] misc: Move compiler tests to run on 'build' runners

This is an experiment. The runners were sometimes running out of memory
building gem5. The builders have more memory to handle this. The runners
have 4-cores so compilation should be faster (note the inclusion of the
`-j$(nproc)`.
