Soren Jorvang bf2bb00f63 Disable the default PIC generation on OS X. This might make for a
minor performance improvement and also possibly make that platform a
little less prone to problems with ABI assumptions in the JIT code,
although I haven't measured the first or seen signs of the latter.

Only the GL context needs to be specifically freed when shutting
down OpenGL. The GL canvas is implicitly freed by wxWindow.
