Workaround ASAN false positive

There is a known ASAN false positive case. If a part of the application
is built with asan and another part is not instrumented, and both parts
use e.g. instrumented std::vector, asan may report non-existent
container overflow. This happens because instrumented and
non-instrumented bits of std::vector, inlined and not, are mixed during
linking, so you end up with incompletely instrumented std::vector.

Workaround the issue by statically linking in libbase, thus its code also
becomes instrumented.
