"ar" invocation failure for android build atop OS X

[pnkfelix]

My best attempt today to try to build a rustc targetting Android, based on the instructions at building for android

This is using the OS X android-ndk-r9c

Configure invocation:
../configure --target=arm-linux-androideabi --android-cross-path=$HOME/opt/ndk_standalone --prefix=~/opt/rust-droid

Build invocation:
time remake -j1 --trace

Failing rustc invocation:
