[LTP] [PATCH v3 2/4] Add support for mixing C and shell code

Hi Cyril,

I hoped testcases/lib/run_tests.sh could be run in CI (and manually).

We have in the toplevel Makefile other test targets, could we add
testcases/lib/run_tests.sh to test-shell target?

1) Add test target to testcases/lib/tests/Makefile (similar to
metadata/tests/Makefile).

test:
	@echo == Run C - shell integration tests ===
	@./run_tests.sh

2) Add test target to testcases/lib/Makefile which would call test target in the
test/ directory (similar to metadata/Makefile).

test:
	$(MAKE) -C $(abs_srcdir)/tests/ test

3) Add testing to the toplevel test-shell target + build dependency to testcases/lib/.

test-shell: lib-all
ifneq ($(build),$(host))
	$(error running tests on cross-compile build not supported)
endif
	$(call _test,-s)
	$(MAKE) -C $(abs_top_builddir)/testcases/lib
	$(MAKE) -C $(abs_top_srcdir)/testcases/lib test

Not sure if there should be some quotes.

Also quotes here.

The rest LGTM, but I'll have a deeper look today or tomorrow and try to play
with it.

Kind regards,
