I will add some configury extensions to libmudflap to allow it to
build for more hosts/targets.  If you are not interested in mudflap
instrumentation, you could simply remove libmudflap from your source
tree.  ("cvs release -d gcc/libmudflap".)

I assume this build was not done with BOOT_CFLAGS=-fmudflap, therefore
this would be an ordinary ssa-branch failure, and not possibly related
to mudflap.
