In commit 88baa78d1f31 ("selftests: remove duplicated all and clean
target"), the "all" target was removed from individual Makefiles and
added to lib.mk.
However the "all" target was added to lib.mk *after* the existing
"runtests" target. This means "runtests" becomes the first (default)
target fo
Currently we can't build some tests, for example:

Both these rules incorrectly use $< (first prerequisite) rather than

one .S file as input. Switch them to using $^.
They also don't include $(CPPFLAGS) and other variables used in the
default rules, which breaks targets that

In benchmarks we need to use $(TEST_GEN_PROGS) after we include lib.mk,

correctly, put back the 'v' and 'f'.
In tm we need to substitute $(OUTPUT) into SIGNAL_CONTEXT_CHK_TES
