android: configure tries to use 32-bit NDK compiler on a 64-bit system

./configure -v -developer-build -xplatform android-g++ -android-ndk /home/rutledge/android-ndk-r8e -android-sdk /home/rutledge/android-sdk-linux -android-ndk-host linux-x86_64 -android-toolchain-version 4.7 -platform linux-g++-64 -nomake tests -nomake examples

(or with much fewer options, even)
