Yes. It is in fact a bad idea to add specific flags just for GTest.

Do not rely on GTest's configure. Just refer to the GTest sources
directly in our build.conf, and let our makefile build it. In fact, this
is the only sane way to eventually make it work on Windows.

We should simply ignore it since we will not be running GTest tests,
we'll be using GTest for running our tests. Hence, as I said above, we
can just ignore the GTest configury and simply compile their sources
into two libraries (libgtest_main and libgtest). Refer to GTest build to
find which sources belong where, but other than that, ignore it.
The GTest sources are completely standalone and do not require any
external dependencies in order to be used as a test framework.

We already have magic in place to see if we need to add -lpthread to the
link lines. And in fact it's irrelevant for building the GTest libraries
-- it only matters when building the test binaries, IIRC.
Whether we want GTest itself to use threads is another question -- I
think the answer is a definite no for now; I can't think of a good
reason to write multithreaded tests at this point.
