[OE-core] [PATCH] ltp: Fix build on x86/musl

[Khem Raj]

In last patch it covered out the non-glibc case well
but did not define else case, when __GLIBC__ is not
defined, as a result errors like

| getcpu01.c:107:41: error: use of undeclared identifier 'sys_support'
|         if (((tst_kvercmp(2, 6, 20)) < 0) || !(sys_support)) {

appeared, fixed it with this updated patch

+Subject: [PATCH 01/25] Check if __GLIBC_PREREQ is defined before using it
 
 __GLIBC_PREREQ is specific to glibc so it should be checked if it is
 defined or not.
