Unslung now fails when building gcc-cross.  I presume this is a result 
of this activity (it build before the Feb 28 commits), but I do not 
understand the issues about sysroot and all well enough to even begin to 
be able to troubleshoot.  Is the patch attached to this original email 
supposed to fix this?  Is there something broken in the recipe, as 
implied by this thread, that I need to fix?  If so, what would that be?

In particular, note the error message which claims that the 
...gcc-3.4.4/usr/include file does not exist.  No, it does not -- it's 
at ...gcc-3.4.4/include instead.
