I haven't yet looked at your patches in detail, but I did also notice
the check on perf_event.h in /usr/src/linux. However, this should have
been fixed with the --with-kernel=$(SYSROOT_DIR).
However, I just now notice that SYSROOT_DIR does not exist here, and I
need to find a better solution. I will investigate that aspect
Ideally we'd indeed merge your work together with these patches. Do
you recall what was still missing or not working with your patches?
