Plastid 0.4.7 completing installation but not importable on OSX

[joshuagryphon]

Two users have reported that Plastid passes installation, but fails during runtime on OSX. This appears to be conda-independent, and occurs even when installing inside virtualenv. After a successful install, import plastid yields:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/username/env/lib/python2.7/site-packages/plastid/__init__.py", line 40, in <module>

Looking into this a bit, it seems like clang is making dynamically-linked libraries, which is weird because on Linux GCC makes static libs for all of Plastid's extensions.

Fixed by removing EXTRA_LINK_ARGS from setup.py. See commit 340e6c6
