Is the lot of those changes just so you can use the "ndk-build" command? 
You know you don't have to use it for android stuff, you can keep using 
existing/traditional build systems. We at Rockbox use our original 
make-based build system in the same way as for all other ports, with the 
exception that the final output is a .so file. This basically just 
required passing -shared on the final linker cmdline. The point is that 
we don't use ndk-build anywhere and this kept the required changes to 
our build system at a minimum.

Best regards.
