[Crash-utility] Heads-up re: ppc64le support in crash-7.0.8

Petr, Michel, et al, I'm currently working on adding ppc64le support for the next upstream crash release. I'm working from a Fedora bugzilla filed by Michel Normand, where he that applied the "crash-gdb-7.6.series" set of patches from the openSUSE distribution. Thanks Michel for doing the initial legwork using the Fedora tree. For the upstream crash utility repo, I do not want to carry the set of 9 patches individually, but similar to the singular gdb-7.6.patch, I plan to concatenate them into a singular gdb-7.6-ppc64le-support.patch. Ideally the contents of the 9 patch files could be added to the gdb-7.6.patch, and I may do that in the future. However, just the crash-gdb-7.6-bound_minimal_symbol.patch in the 9-part set is so large and intrusive (touching dozens of arch-neutral files) that I am paranoid about breaking something, or altering behavior for the other architectures. So I plan to take a more cautious route for now, and only apply the gdb-7.6-ppc64le-support.patch if the build host is ppc64le. Thanks, Dave
