Fixed bug 2802 - [patch] Fix android build compiling in wrong filesystem implementation

Jonas Kulla

The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c.

I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.
