It could be weeks before the last gcc patches filter down to F15, if 
ever.  I suggest we start koji with a custom srpm and move on to an 
update once it becomes available.

Per our IRC conversation, the second patch in 50521, "patch to honour 
STRICT_ALIGNMENT," breaks the gcc build.  Midway through, xgcc is used 
to generate an executable which segfaults.  The build works with 50521's 
"proposal patch" however.  I have not tested the result.
