Qt 5.1.2 (git) android x86 configure problem

[thesourcehim]

Hello, I'm trying to run configure like this:
./configure -prefix /mnt/d/android/Qt5/x86 -xplatform android-g++ -debug-and-release -opensource -shared -openssl -I /mnt/d/android/openssl/include -L /mnt/d/android/openssl/libs/x86 -nomake examples -android-ndk /mnt/d/android-ndk-r8e -android-sdk /mnt/d/adt-bundle-linux-x86_64-20130717/sdk -android-ndk-platform android-9 -android-arch x86 -android-toolchain-version 4.7

However during initial tools build configure is trying to use x86-g++ instead of i686-linux-android-g++. Setting environment variables ANDROID_NDK_TOOLS_PREFIX and NDK_TOOLS_PREFIX doesn't help.
