I don't know how that would work with the main kernel Makefile
but we do those kinds of tests in perf before we build it so
that we can save ourselves the time spent on a failed build:
2209001fd895e8932ae2c85bfca233758234499a.

This should probably work if you add a prerequisite target which runs
early in the build process and checks for all the userspace tools
required for the build.

Thanks.
