    _______________________________________________________

Details:

This is a regression from GNU make 4.0. The make target

clean:
        rm lib/*.{o,a}

fails to remove files lib/foo.o, lib/bar.o, and lib/libfoobar.a  because
lib/*.{o,a} does not glob lib/*.o and lib/*.a, as is its intention.

This is very different from how the shell globs things:
$ echo lib/*.{o,a}
lib/foo.o lib/bar.o lib/libfoobar.a
