[CentOS] Funny stuff in SELinux -- /usr/lib/libGL.so.1.2.#prelink#.4GxqM1

Received this SELinux warning:

Summary:

SELinux is preventing ld-linux.so.2 from loading
/usr/lib/libGL.so.1.2.#prelink#.4GxqM1 which requires text relocation.

Detailed Description:

The ld-linux.so.2 application attempted to load
/usr/lib/libGL.so.1.2.#prelink#.4GxqM1 which requires text relocation.
This is a
potential security problem. Most libraries do not need this permission.
Libraries are sometimes coded incorrectly and request this permission.
The
SELinux Memory Protection Tests
(http://people.redhat.com/drepper/selinux-mem.html) web page explains
how to
remove this requirement. You can configure SELinux temporarily to allow
/usr/lib/libGL.so.1.2.#prelink#.4GxqM1 to use relocation as a
workaround, until
the library is fixed. Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this
package.

Allowing Access:

If you trust /usr/lib/libGL.so.1.2.#prelink#.4GxqM1 to run correctly,
you can
change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/usr/lib/libGL.so.1.2.#prelink#.4GxqM1'" You must also change the
default file
context files on the system in order to preserve them even on a full
relabel.
"semanage fcontext -a -t textrel_shlib_t
'/usr/lib/libGL.so.1.2.#prelink#.4GxqM1'"

Fix Command:

chcon -t textrel_shlib_t '/usr/lib/libGL.so.1.2.#prelink#.4GxqM1'

A few minutes later I got the same warning but it was about

SELinux is preventing ld-linux.so.2 from loading
/usr/lib/libGL.so.1.2.#prelink#.1brWwM which requires text relocation.


I ran rpm -VA and received the following:

with the following line on the error output:

prelink: /usr/lib/libGL.so.1.2.#prelink#.4GxqM1 Could not trace symbol
resolving


After receiving the second SELinux notice, rpm -Va gave the same results
except it referenced .1brWwM

prelink: /usr/lib/libGL.so.1.2.#prelink#.1brWwM Could not trace symbol
resolving



What are the two files:

/usr/lib/libGL.so.1.2.#prelink#.4GxqM1
/usr/lib/libGL.so.1.2.#prelink#.1brWwM

And what is going on with them?
