Looks like when it gets built via ./libs it works, but if it's pulled
as dependency first, it fails:

# make -C $(pwd)/../ltp-build/testcases/kernel/syscalls/set_mempolicy/ -f $(pwd)/testcases/kernel/syscalls/set_mempolicy/Makefile top_srcdir=$(pwd) top_builddir=$(pwd)/../ltp-build
make: Entering directory `/root/ltp-build/testcases/kernel/syscalls/set_mempolicy'
make -C "/root/ltp-build/libs/libltpnuma" -f "/root/ltp-build/libs/libltpnuma/Makefile" all
make[1]: Entering directory `/root/ltp-build/libs/libltpnuma'
make[1]: /root/ltp-build/libs/libltpnuma/Makefile: No such file or directory
make[1]: *** No rule to make target `/root/ltp-build/libs/libltpnuma/Makefile'.  Stop.
make[1]: Leaving directory `/root/ltp-build/libs/libltpnuma'
make: *** [/root/ltp-build/libs/libltpnuma/libltpnuma.a] Error 2
make: Leaving directory `/root/ltp-build/testcases/kernel/syscalls/set_mempolicy'

Maybe something like this to fix it?
