Enable libmudflap for bfin-uclinux

- Subject: Enable libmudflap for bfin-uclinux
I've committed the following patch, which enables mudflap on
bfin-uclinux. The MFWRAP_SPEC needed overriding so that we always wrap
symbols the way mudflap expects for a static link (no real shared
libraries with flat-format binaries).
I've not enabled other *-uclinux targets, since they probably need the
same specs change.
Bootstrapped on i686-linux.
Bernd
