[LTP] [PATCH 1/1] Makefile: Add make 'modules' target

[Petr Vorel]

LTP contains few kernel modules and tests which are using them.  These
require to be built with the same kernel headers as the running kernel
(SUT). Sometimes the best way to achieve this is to compile them on the
SUT. Add make 'modules' target to make it easier to build them.

Hi all,

We build these modules in openQA during testing.  Hope you don't mind to
keep the list of directories with kernel modules in LTP (instead of
maintaining it outside). And hopefully it helps others which might face
the same problem.

I tempted to add also 'make install' to the target to shortcut
'make modules && make modules install' to just 'make modules', but that
would not be a clean and consistent approach.

Kind regards,
Petr

+'make modules' target is a shortcut to build these kernel modules and tests.
