[LTP] [PATCH 2/2 v2] libs: Hook up libs into the build system

[Petr Vorel]

Hi Jan, Cyril,

> I tested v2 as far back as RHEL6.2, ACK.
Jan, have you tested out of tree build?

Still failing [1], mostly for out-of-tree builds [2]:
make: Entering directory '/usr/src/ltp-build'
make -C "lib" \
	-f "/usr/src/ltp/lib/Makefile" all
make -C "libs" \
	-f "/usr/src/ltp/libs/Makefile" all
make[1]: Entering directory '/usr/src/ltp-build/lib'
mkdir -m 00755 -p "newlib_tests"
make[1]: Entering directory '/usr/src/ltp-build'
make[1]: *** libs: No such file or directory.  Stop.
make[1]: Leaving directory '/usr/src/ltp-build'
/usr/src/ltp/Makefile:114: recipe for target 'libs-all' failed
make: *** [libs-all] Error 2
make: *** Waiting for unfinished jobs....

And i386 for Debian has still the same error [3]:
/usr/src/ltp/libs/libltpnuma/tst_numa.c:200: undefined /tmp/ccO9srN7.o: In function `verify_set_mempolicy':
/usr/src/ltp/testcases/kernel/syscalls/set_mempolicy/set_mempolicy04.c:105: undefined reference to `numa_allocate_nodemask'

/usr/src/ltp/testcases/kernel/syscalls/set_mempolicy/set_mempolicy04.c:112: undefined reference to `set_mempolicy'
