perhaps one of the build maintainers has a suggestion.  For the time
being, I'll juts continue with --enable-libmudflap.

I've now filed

libmudflap/49549	Use of --noinhibit-exec is unportable
libmudflap/49550	Many libmudflap tests fail on Solaris 11/x86

The second one almost certainly covers a couple of different issues, but
I cannot identify them yet, so any help is appreciated.
