patches for building with Android NDK

[Tias]

Dear Busybox developers,

Since Rob Walker's patch[1], building busybox with the Android NDK has 
really become dead simple; no special hacks or external libraries are 
needed anymore.

However, a large number of applets can currently not be built.

I started documenting why applets don't build, as well as collecting 
patches from different sources, that fix the issues:
https://github.com/tias/android-busybox-ndk
https://github.com/tias/android-busybox-ndk/tree/master/patches

I would love to see the ideas behind these patches integrated, so that a 
standard busybox build can be used in the many android open-source 
projects that depend on it (and currently use a statically built 
third-party blob).


However, I am unfamiliar with the coding practices of the busybox 
community, and many of these patches were written to fix the build and 
not necessarily to get merged upstream.
I consider my work in collecting these patches as just a first step.
Hence, I would like to solicit feedback on what can and can not be 
merged, and what would be required to get these fixes in.


Thanks in advance,
Tias
