ATI radeon 3450 is affected by this bug [1]. The following patch submitted by dim@ allows to build with Clang and avoids the duplicate symbol definitions.

Workaround Clang issue with Mesa on i386

While the LLVM bug is fixed upstream, Dimitry Andric posted a Mesa patch on freebsd-x11@ to workaround the problem:
http://lists.freebsd.org/pipermail/freebsd-x11/2014-July/014844.html

It was tested successfully by the OP:

I attach this patch to this report.

Almost 2 weeks have elapsed. We have any update on this? IMHO the bug status needs to change to "Patch ready".

Sorry for not getting back to you.  I've been busy elsewhere, and I believe the rest of the x11@ team have a lot on their plate as well.
Changes to libGL and other graphics related ports with lots of dependencies require a great deal of care, to not break other things.  We will look at this patch as time permits.

Hi Niclas,

After your clarification, we leave this bug in the pipeline :)

I can confirm that it does allow me to build graphics/libGL on fresh -CURRENT/i386 with Clang.  With newly built libGL, I was able to get simple OpenGL apps to run without segfaulting I've reported [1] earlier, but "real" apps (Doom Legacy, Quake2) still crash upon startup.  (It might be unrelated though.)

Author: kwm
Date: Fri Oct 17 09:53:18 UTC 2014
New revision: 371035
URL: https://svnweb.freebsd.org/changeset/ports/371035

Log:
  Update Mesa ports to new default of 9.1.7 and more recent version to 10.3.0.

  The port will switch to the newer version if hw context is available in the
  i915kms driver.

  - Get ride of WITH_NEW_XORG.
  - Use @comment in plist to ignore unwanted files in the stagedir, instead of
    trying to remove them in post-install.
  - Bump portrevision of 9.1.7 due to dependency changes.
  - Drop :keepla from USES=libtool.
  - Drop @dirrm[try] from plists
  - Give dri propper options, with pkg-help for additional information.
  - Make separate plist for dri for the different versions, the combined plist
    was headache inducing.
  - Add "workaround" patches to allow clang to build the dri port on i386 [1].
    USE_GCC is now only needed for 8.x.
  - Add gbm port and USE_GL switch for it.
