Medium severity: make -C testcases/kernel/syscalls -j4 SUBDIRS=getuid
now exits 2 because the shared-library sub-make inherits SUBDIRS=getuid
and looks for libs/getuid/Makefile. The same command succeeds before this
patch; keep the test-directory selection out of shared-library sub-makes.

Verdict - Needs revision
