The patch was already included in following gits:
"ltp-dev-121ad2a296f4ade04e2c2e351820df32a6c441d5.tar.gz" 
"ltp-dev-8b0ca7e9a5e7dcab8d7cbad0b6f0c808798bdc53.tar.gz"
and I tried to build with these gits instead of the patch.

POSIX "sched_yield/1-1.c" build successed in RHEL5.5 (x86, x86_64, ia64), 
but failed in RHEL4.8 (x86, x86_64, ia64):
------------(RHEL5.5 x86)
conformance/interfaces/sched_yield/1-1 compile PASSED
------------

------------(RHEL4.8 x86)
conformance/interfaces/sched_yield/1-1 compile FAILED; SKIPPING
In file included from ../../../conformance/interfaces/sched_yield/1-1.c:35:
../../../include/posixtest.h:23:2: warning: #warning "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'
/tmp/ccuhCnVY.o(.text+0x1c1): In function `set_thread_affinity':
: undefined reference to `pthread_setaffinity_np'
collect2: ld returned 1 exit status
------------

But, in all my RHEL5.5/4.8 systems, this revision brought the build
successes 
of the following testsets that were concern from the past:
 - "pthread_attr_setstack/2-1.c"
 - "pthread_attr_setstacksize/2-1.c"

Now in all my RHEL5.5 systems, all build failes were settled by this
revision.



Thank you--
