When doing "make kselftest TARGETS=bpf -j12", bpf progs end up being compiled sequentially and thus slowly. The reason is that parent make (tools/testing/selftests/Makefile) does not share its jobserver with child make (tools/testing/selftests/bpf/Makefile), therefore the latter runs with -j1. Change all instances of "make" to "$(MAKE)", so that the whole make hierarchy runs using a single jobserver.
