[PATCH] Fix building Asan and common sanitizers tests on FreeBSD 9.2

[Viktor Kutuzov]

Hi kcc, samsonov,

We need to add the "-lc++" option explicitly to the LINKFLAGS for some of the Asan and common sanitizers tests (e.g., the -with-calls ones) on FreeBSD 9.2. It looks like it's fixed for upcoming versions of FreeBSD: http://lists.freebsd.org/pipermail/svn-src-stable-9/2012-May/001855.html .
