Hm. Clearly this needs more work. But I don't really like having checks for
MSBUILDDIR in individual tests - we should do this somewhere more central.
Afaictl the windows build just installs libpq_pipeline.exe. If we make sure
that on !msvc builds CURDIR is on PATH and on msvc temp_install/bin/ is on
PATH (which it should already be), then we should be good?

I guess the reason this didn't work for me before was that I invoked
install.pl from the top directory, which then didn't install
libpq_pipeline.exe, because of the config.pl issue I mentioned somewhere?
