[OE-core] [PATCH 02/12] util-linux: remove erroneous patch (qsort_r)

[André Draszik]

From: André Draszik <andre.draszik at jci.com>

The patch in question is patching the code to use
qsort() instead of qsort_r(), without adopting the
compare function. This is a major issue, because
the compare function as written is evaluating /
accessing a third argument, which is not passed
with this OE patch, causing access to random
memory.

Given this patch was added so as to support (old)
linux (host) distros which might not provide
qsort_r(), according to the git history, and given
these days util-linux detects availability of
qsort_r() during configure phase, and given musl
builds (which doesn't provide qsort_r() either)
work without problem, the right solution is to
simply drop this invalid patch.

Do so.

-qsort_r() was added to glibc in version 2.8, so there is no qsort_r() on
-the host like CentOS 5.x.
