zos: fix non-Release builds

Browse Source 
z/OS doesn't support POSIX semaphores. On Release builds the code
paths that reference POSIX semaphore functions (e.g. sem_init())
are optimized away so linking succeeds but on a non-Release build
the references to the unavailable functions result in unresolved
symbol errors.

Stub the unavailable POSIX semaphore functions on z/OS as so the
code can link on non-Release builds.
