PATCH: loadable modules on Haiku

[Oliver Kiddle <opk@xxxxxxx>]

The lack of loadable modules in a Haiku build is due to using -nostart
instead of -shared. I guess their compiler used to be special but that
was unsustainable. The modules are there for their build of zsh. With
this, zpty also works so more of the test cases.
