[uml-devel] more checkins

[Jeff D. <jd...@ka...>]

hostfs now mostly works.  The main exceptions are running executables and 
mknod.  Also, it gets impossible to unmount after enough things are done 
inside it.

Fixed that linking problem.  It turned out to be triggered by doing a 
profiling build.

I think I fixed the crash reported by James Stevenson (he hasn't told me 
whether this fix changes anything, though).

"fake_arch" is now history.  I ran into one build problem too many caused by 
UML reporting its architecture as "um".  So, it now claims its architecture is 
"i386".
