bah, this happens when you do a parallel build. --jobserver-fds is passed in MAKEFLAGS, and the test for sharedmods turns on the quiet mode, because it matches just *s* in MAKEFLAGS :-/

The patch tries to parse MAKEFLAGS using getopt, and if getopt is not available, falls back to MAKEFLAGS, and then tries to match -s.

The only downside is that you won't get a quiet build, if you don't have getopt, and pass MAKEFLAGS options as a combined option (e.g. -fs).
