Allow for artchitecture optimized implementations
The following can be used to disable categories of APIs supported
by the OS. If the compiler supports weak functions, then it
should not be necessary to disable functions unless you want to
restrict usage of those APIs.
There are certain dependency relationships in these features.
o mq_notify logic depends on signals to awaken tasks
waiting for queues to become full or empty.
o pthread_condtimedwait() depends on signals to wake
up waiting tasks.

Allow for architecture optimized implementations

following to improve sysem performance
