[OE-core] [PATCH 1/2] glib-2.0: Don't check function qsort_r

[Xiaofeng Yan]

From: Xiaofeng Yan <xiaofeng.yan at windriver.com>

function "g_qsort_with_data" has two kinds of realization. One calls qsort_r
from libglib, the other realize itself.
qsort_r from libglib cause sort error.
For fixing this problem no checking "qsort_r" in configure.ac.

[YOCTO #1959]
