bug#50931: 28.0.50; Tramp test suites fails when remote is MacOS

[Damien Merenne]

When running the tramp test suite using a MacOS remote host, some test
fails, according to the tramp maintainer, it seems related to the native
compilation feature.

Running

$ env REMOTE_TEMPORARY_FILE_DIRECTORY='/ssh:laptop.lan:/tmp' make -C test
tramp-tests

Here are the traces of the failing tests whichall fails in
`comp--native-compile`
