[LTP] [RFC PATCH v2 1/2] Add 'make check' and clang-check to build system

[Petr Vorel <pvorel@suse.cz>]

Hi Richie,

> Allows the user to run 'make check' to check all source files or
> 'make check-<target>' to check one source file corresponding to a
> target.

> Adds makefile pieces for tools/clang-check/main which will be a
> libclang based tool. By default this is ran by 'make check'.

> In theory allows other tools to be specified with
> 'make CHECK=tool CHECK_FLAGS=<args> check...'. e.g. 'make CHECK=sparse
> CHECK_FLAGS= check-tst_cgroup'

one more proposal (addition to Metan's fix [1]):
how about to add top level make check target:
