I don't think any of the packages are going to be an issue.  None of
them are critical path packages or anything especially important,
except possible llvm.

I did initially look at backporting just the single compiler patch[1].
However since it quickly became obvious that it was a change to the
register allocator, it was clear that everything that had been built
from that needed to be recompiled.  Oh well ..
