Hm. So the kernel I tried to build this morning failed on ARM:
http://koji.fedoraproject.org/koji/getfile?taskID=6723963&name=build.log
That cross-built locally (gcc 4.8.1) here fine before I sent it to
koji. Anyone have any ideas on that?
An f20 scratch build of the same SRPM has progressed past the failure
point above. I suppose I'll dig into what changed in this regard and
see if there's a fix that works for both. In the meantime, if anyone
knows what might have changed in gcc 4.9 to cause this, please speak
up.
