People don't do it because that warnings are hidden in huge log. It will
be good to run
sparse too.

Yes, I agree that make no sense to add all syscalls test for example to
Kconfig but
I can imagine tests for noMMU as are currently wrote in Makefile. For
example will be good for all to know
why are some tests exclude for noMMU.
Maybe any handling for older glibc with missing some syscalls to prevent
build failure.
Setup global cflags and cross compiler.
If you look to runtest for testing description, make sense to me have
all that filenames as Kconfig option and
enable/disable that tests.

this point depended on descriptions below. I think we talked about once
in past.

There are a lot of additions like CFLAGS, LDLIBS.
CFLAGS += -I../../../../include -Wall
LDLIBS += -L../../../../lib -lltp

I think that install and clean parts could be possible to clean too and
have Makefiles with
one or two lines  like  test-y +=test_name

Is it possible to do with Kbuild? That the same question as I had in
previous email.

yes, but for example in LTP we don't need to use many custom Makefiles
(There are some like ebizzy, boost, preempt-test and some others)
the rest are LTP specific Makefiles.
