__lsan::DoLeakCheck and  __lsan::InitCommonLsan are defined in
lsan_common.cc, which does not get compiled in the Makefile based
build.

This is breaking the Chromium build:
http://build.chromium.org/p/tryserver.chromium/builders/linux_chromeos_asan/builds/6839/steps/compile/logs/stdio

Any idea how to fix this?

Thanks,
