Yes, this happens only with Homebrew and it started happening when
Homebrew upgraded libgccjit (and gcc) to version 12.

Previously, Homebrew was installing the libgccjit libraries in

    $HOMEBREW_PREFIX/opt/libgccjit/lib/gcc/${major_version}

Whereas it now installs them in

    $HOMEBREW_PREFIX/opt/libgccjit/lib/gcc/current
    $HOMEBREW_PREFIX/opt/libgccjit/lib/gcc/${major_version}

with the latter being a symlink to the former.  This breaks the
configure script which expects only a single libdir to be found; it
now finds two and ends up with an erroneous invocation (i.e.
`-L${libdir1} ${libdir2}' as opposed to `-L${libdir}').

Best regards,
Dario
