I made a patch to implement all three things for musl on android.

I do not post it here as attachment to this mail because it normally
should not be integrated with musl. The patch itself is here:
http://lynxlynx.tk/prg/patches/musl-1.1.4_android.patch, notes about
it: http://lynxlynx.tk/eng/musl_android/.

Patch is invasive enough I think and not optimized and I agree with Rich
that it must go as a special treat. I tried however move away all
translating code to src/android and headers to include/android.

Patch is still in it's alpha stage, and probably will be changed often.

Modifications made for musl 1.1.4.

If anyone interested to audit it - welcome!
