sys-devel/gcc-12.1.0: workaround compilation issue on arm64-darwin

For some reason when flex invokes m4 during bootstrap of gcc, it fails
which results in an empty file, causing compilation to fail.  This is a
really weird issue only happening on arm64/Apple SI, so just use the
host flex which seems to work correctly.
