[PATCH 5/6] kbuild: Don't pass -rR to selftest makefiles

[Michael Ellerman]

The makefiles under tools/testing/selftests are not real kbuild
makefiles, they are regular stand alone makefiles. As such they *do*
want all the standard implicit rules and variables defined.

So before calling those makefiles, filter -rR out of MAKEFLAGS.

Without this not all the selftests are built correctly when called via
the top-level Makefile.
