I now see that Mesa (libGL, dri, ...) is built with GCC on i386; never
noticed that before. See graphics/libGL/bsd.mesalib.mk:

# i386 triggers clang bug 19778. This happens with clang 3.4.1 and older.
. if ${ARCH} == i386
USE_GCC=yes
. endif

The bug is described here:
http://llvm.org/bugs/show_bug.cgi?id=19778

I add Dimitry into the loop: Dimitry, do you have any news for this
Clang bug?

Buildling Mesa with GCC causes the usual libc++ vs. libstdc++
incompatibilty:

libGL error: dlopen /usr/local/lib/dri/r600_dri.so failed
(/usr/local/lib/dri/r600_dri.so: Undefined symbol
"_ZN4llvm13EngineBuilder12selectTargetERKNS_6TripleENS_9StringRefES4_RKNS_15SmallVectorImplISsEE")
