This compiled and worked on Android before, if you didn't care about
PHYSFS_getBaseDir() and PHYSFS_getPrefDir() being useful. Now you can pass
PHYSFS_init() some necessary Android objects to solve this. Passing NULL
to PHYSFS_init is acceptable and will simply report "/" for the base dir and
prefdir, under the assumption that the app queried the OS for these directly
instead.
