sys-libs/libomp: Disallow kernels with PDU scheduler
The PDU scheduler (used e.g. in current versions of -pf kernel) does not
implement the sched_yield() call which is used by the OpenMP
implementation to switch between threads. As a result, using OpenMP with
this scheduler results in horrible performance with 100% CPU usage
on looped noop syscall calls.
Closes: https://bugs.gentoo.org/638410
