By default ccache checks the compiler 'mtime' to determine if it should
invalidate the cache. On FreeBSD the 'mtime' reflects when the compiler
package was installed, rather than when it was built. IOW, on throwaway
CI VMs, the 'mtime' changes on every single job and is thus useless.
It could validate the compiler binary content, but validating the
compiler version string is less CPU intensive.
