Bug#714294: libc6: applications linked with proprietary nvidia modules get SEGV because tls version of library is not found

Package: libc6
Version: 2.17-3
Severity: normal

Dear Maintainer,

I am seeing SEGV at a startup for _all_ applications which are linked
to libGL served by a proprietary NVIDIA driver. At first I thought this
was the NVIDIA issue but then it turned out that the issue is caused by
linker (or at least this is my understanding now).

NVIDIA installer provides two versions of nvidia-tls library:
$ file /usr/lib/libnvidia-tls.so.310.44
/usr/lib/libnvidia-tls.so.310.44: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, for GNU/Linux 2.2.5, stripped
$ file /usr/lib/tls/libnvidia-tls.so.310.44
/usr/lib/tls/libnvidia-tls.so.310.44: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, for GNU/Linux 2.3.99, stripped

I would have expected that /usr/lib/tls variant would be picked up
automagically.
$ /sbin/ldconfig -p | grep tls
        libnvidia-tls.so.310.44 (libc6, hwcap: 0x8000000000000000, ABI OS: Linux 2.3.99) => /usr/lib/tls/libnvidia-tls.so.310.44
        libnvidia-tls.so.310.44 (libc6, ABI OS: Linux 2.2.5) => /usr/lib/libnvidia-tls.so.310.44

and
$ /sbin/ldconfig -v | grep -v ^$'\t' 2>/dev/null

/usr/lib/i686/cmov: (hwcap: 0x0008000000008000)

suggest that /usr/lib/tls should be honored. For some reason it is not
though.

SEGV

$ LD_LIBRARY_PATH=/usr/lib/tls:/usr/lib  ./main
Yep

Is this a misconfiguration on my end or the glibc doesn't honor tls/
directory?
