#67525: libgcc12: odd state failures when trying to clean or install a port

--------------------+----------------------
 I get this error when trying to install `libgcc12` (though I can't be 100%
 certain as it only happens on the CI system.

 I've seen this happen with other ports as well.

 {{{
 Error: Unable to execute port: couldn't open
 "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_lang_gcc12/libgcc12/work/.macports.libgcc12.state":
 permission denied
 }}}

 Any ideas why macports is failing in this unintuitive and very hard to
 code around way?
