What's going wrong seems to simply be that the android/bionic runtime 
linker doesn't support symbol versioning at all, the toolchain seems to 
produce correct binaries.

Attached is two patch suggestions implementing this. The first one works 
by setting --target-os=linux-android, and disabling symbol versioning in 
that case. The other one checks if $cross_prefix includes androideabi. An 
even more accurate, but more messy, solution would be to link a full 
binary, then examine the built binary and see if it specifies 
/system/bin/linker as its dynamic linker. (I'm not totally sure of how to 
achieve that cleanly, though.)
