Cirrus: Native OSX Build

These changes execute the cross-compile build naively on an OSX VM to
more thoroughly verify multi-platform support (other than on Linux). In
other words, it better confirms that any Linux-only changes do not leak
into non-Linux environments.  This change also enables greatly
simplifying automation scripts, as there is no longer any need to
support/check the `$CROSS_TARGET` variable.
