In the toplevel Makefile:
kselftest-%: headers FORCE
$(Q)$(MAKE) -C $(srctree)/tools/testing/selftests $*
So running "make kselftest-all" to build the self tests should have
already caused make to build the "headers" target, which puts the
headers into usr/include.
I don't think it's supported to build self tests w/o invoking the
toplevel Makefile: many other self tests use KHDR_INCLUDES as well, so
generally building with something like "make -C tools/testing/selftests"
just won't work.
