Subject: [PATCH] perf: turn off compiler warnings for flex and bison generated files
We don't know what types of warnings different versions of flex and bison
combined with different versions of gcc is going to generate, so just punt and
don't warn about anything.
This fixes the build of perf for me on an openSUSE 12.1 system.

Note, I don't really like this, but how else are we going to ensure that we
catch all warnings? Pick them off one by one? Better ideas are accepted...
