For the time being I've disabled PCH support in Boost.Math when
--remove-test-targets is on the command line. Hopefully we'll actually
get some regression test results now at the expense of even slower build

This is still the wrong fix though: we shouldn't break a documented
feature (PCH) with an undocumented one.
