Side note: its' not even about testing.

The error message makes it clear that this is garbage and should never
be merged even if it were to compile.

There is not a way in hell that it is correct that a 'perf' tool build
should ever even look at the vmlinux binary to build.

The fact that it does shows that something is seriously wrong in
perf-tool land, and I will not be touching any pulls until that
fundamental mistake is entirely gone.

The vmlinux image that is present in my tree (ie
/home/torvalds/v2.6/linux/vmlinux) is a test build with an insane
config. And the fact that the perf tool even looks at it is seriously
broken.

Whatever you are doing - stop it right now.
