Commit glibc-2.14~10 disallowed rtld self loading to avoid a segfault
that used to happen when rtld was loading itself in normal mode.
Unfortunately, that commit disallowed all modes of self loading,
including those that used to work before. This change limits the check
for self loading to normal mode only, so that instruments like ldd could
handle rtld properly.

[Impact / Justification]
To be fair, this bug is (mostly) cosmetic, but when tools exit non-zero in scary ways, it can have knock-on effects elsewhere (to custom scripting, or just frightened users). The fix here is targeted, "obviously correct", and easily auditable, so I figured I'd pull it back to the LTS for a bit of polish.
[Test Case]
The SRU patch includes an addition to the glibc testsuite that tests that ld.so can now load itself correctly in a few different ways, but the easiest user verification is to run:
ldd /lib/ld-linux.so.2 (or /lib64/ld-linux-x86-64.so.2 on amd64)
And witness it fail before the upgrade, and work after.
[Regression Potential]
Regression potential here is low, the patch is from upstream, very simple, and it's quite clear what it does.
