[LTP] POSIX "sched_yield/1-1.c" build failed

["Mitani" <mitani@ryobi.co.jp>]

Hi,

POSIX "open_posix_testsuite/conformance/interfaces/sched_yield/1-1.c" 
build failed in RHEL4.8 (x86, x86_64, ia64):
------------
conformance/interfaces/sched_yield/1-1 compile FAILED; SKIPPING In file
included from ../../../conformance/interfaces/sched_yield/1-1.c:35:
../../../include/posixtest.h:14:2: #error "Contains GNU-isms that need
fixing."
../../../conformance/interfaces/sched_yield/1-1.c: In function
`set_thread_affinity':
../../../conformance/interfaces/sched_yield/1-1.c:91: warning: implicit
declaration of function `pthread_setaffinity_np'
------------

This testset seems to test "sched_yield()", and uses "sched_setafinity()" 
for CPU fixing.
I tried to remove "_GNU_SOURCE" definition from "sched_yield/1-1.c".
But "sched_setafinity()" needs "_GNU_SOURCE".
"sched_setafinity()" is necessary for this testset, and I considered the
substitution for "sched_setafinity()".
But I don't have any ideas. There is no function to be substitute for
"sched_setafinity()" by POSIX conformity, I think.
