Rawhide PPC64

[Jerry James]

I'm still trying to debug my PPC64 problem with GCL on Rawhide.  I
figured out how to get around the SELinux problem, built the software
up to the point where it segfaults on the koji builder, installed gdb
in the mock root, ran mock --shell, and did this:

-------------------------------------------------------------------------------

So I see a couple of things that concern me.  First, I don't know why
rpmdb is involved at all [1], but what's up with the "rpmdb: munmap:
Invalid argument" line?  Second, gdb segfaulted!  I can't diagnose a
GCL segfault with a segfaulting gdb.  Does anyone have a Rawhide PPC64
machine running (i.e., not just mock)?  If so, does gdb work there?

Footnotes:
[1] Is this so gdb can find the debuginfo?
