bug#52431: 29.0.50; Semantic bovine GCC tests failing on macOS

[Philipp]

On my macOS Monterey machine, the tests
lisp/cedet/semantic/bovine/gcc-tests fail with the following logs:

Running 2 tests (2021-12-11 14:22:33+0100, selector `(not (or (tag 
:expensive-test) (tag :unstable) (tag :nativecomp)))')

1 unexpected results:

I guess this test assumes a specific output from the compiler, which is
only present on GNU/Linux?
