Submitted by Debarshi Ray Link to original bug (#736737)
Description
From: https://bugzilla.redhat.com/show_bug.cgi?id=1141470:
"This package appears to include a private copy of valgrind.h. In the latest relase of valgrind 3.10.0 a bug was fixed for ppc32 and support was added for aarch64 and ppc64le. Please either update the private copy of valgrind.h (memcheck.h, callgrind.h, etc) or (better) make your package BuildRequires: valgrind-devel and use the system installed headers."
