Which platform ? I cannot find the lib neither:
http://packages.debian.org/experimental/amd64/libclang-common-dev/filelist
nor:
http://packages.debian.org/experimental/i386/libclang-common-dev/filelist

Here is the actual link line:

I am guessing you have
/usr/bin/../lib/clang/3.2/lib/linux/libclang_rt.ubsan-x86_64.a but I
cannot find where your copy is coming from ...

As a side note, I am including other dists reports:

https://bugs.gentoo.org/show_bug.cgi?id=448244
https://bugs.archlinux.org/task/33208

-> they mention use of cmake to get ubsan lib
