[LTP] [PATCH 2/4] openposix: Makefile: Add the standard "maintainer-clean" target

[Petr Vorel]

Hi Ricardo,

> The include/mk/automake.mk file define the standard "maintainer-clean" and
> "ac-maintainer-clean" targets and therein it calls the same targets under
> each AUTOCONFED_SUBDIRS, but in the case of the openposix test suite, they
> don't exist. Add them and also remove some dangling files in ac-clean.

> This fixes the following error when calling `make maintainer-clean` from
> the project's top level directory:

> make[1]: Entering directory './testcases/open_posix_testsuite'
> make[1]: *** No rule to make target 'ac-maintainer-clean'.  Stop.
> make[1]: Leaving directory './testcases/open_posix_testsuite'
> make: *** [./include/mk/automake.mk:68: ac-maintainer-clean] Error 2

Thanks for fixing dark corners of LTP build system.

What a strange target name. Obviously it was meant to be run before release
file, but it was not even called in Makefile.release which I removed in
1088d93d99.

I was thinking whether we really need this target. Maybe it could be part of
distclean.

Kind regards,
Petr
