Build static xhpast
Summary:
Statically links the xhpast binary. On my system, this makes it
increase in size from ~800kb to ~2000kb, which isn't a big deal.
This is also a horrible hack, but a quick one; we should really just be
more careful to build an xhpast that will actually run.
Test Plan: Built a working xhpast as described by the build script.
