Hello,

I'm seeing this build failure, any idea what is the issue?  I've cleared my ccache (ccache --clear)
but that did not help.  A pull from this morning builds on Fedora-29 with same .config file.  I tried
that same commit on my F32 system to no success, so it seems like it might be something with
my F32 compiler/system.
