several patches for uclibc ng
I've got several patches to fix ltp/openmp/uclibc-ng-test testcase fail on c-sky. - fix a ltp testcase. - fix the problem that pthread creat will fail when libomp is linked before libc, the variable pagesize is not init. - fix tst-cancel4 and tst-cancel16. tst-cancelx4 and tst-cancelx16 still fail with this patch applied, cleanup handler is not called for open/creat/fcntl, seems some thing wrong with unwind, I haven't check the rootcause yet.
