Bug#42524: Function pthread_setschedprio() is defined but seems broken on i5/OS PASE
The problem is that MySQL use of pthread_setschedprio is not
supported by i5/OS and the default system behavior for unsupported
calls is to emit a SIGILL signal which causes the server to
abort.
The solution is to treat the pthread_setschedprio as inexistent
when compiling binaries for i5/OS. This also does not invalidate
the fix for bug 38477 as the only supported dispatch class is
SCHED_OTHER (which is passed to pthread_setschedparam).
configure.in:
Skip pthread_setschedprio check on i5/OS.
