Subject: [PATCH] Filter out link-time optimization

Python 3.7 adds some new cflags to "python3-config --cflags" and perf is

picking these up for a subset of the files it builds. These include

-flto, but nothing else is built with link-time optimization and the

linker is not happy about this. This is a quick fix since Python 3.7 is

about to be merged into Rawhide.
