[tree-ssa mudflap] bad 'errno' registration

[Eyal Lebedinsky]

The recent wrappers patch has a few lines that differ from what I
submitted, and one causes an unregister assert failure:

In mf-hooks.c:2374 we register the thread 'errno' as type
__MF_TYPE_STATIC which is wrong. I used __MF_TYPE_GUESS
(which works) but maybe there is another better type -
I do not know.
