This patch enables building and running TSan unit tests on OS X.  There are several changes:

* Move the detection of `OSX_SYSROOT_FLAG` to `config-ix.cmake` so it becomes a global-scope variable.
* Add building a static version of the runtime and link it with the unit tests.
* Modify `tsan_test_util_linux.cc` to be Darwin-compatible and add it into the OS X build.  In a subsequent commit, I'll rename the file to `tsan_test_util_posix.cc`.
* Use `symbolize=false:abort_on_error=0` as default `TSAN_OPTIONS` to speed up the unit tests significantly.
* In `tsan_clock_test.cc`, replace `CLOCK_MONOTONIC` with `gettimeofday`, which is available on OS X.
