Could not uniquely determine machine name

[GoogleCodeExporter]

What steps will reproduce the problem?
Use the latest android.toolchain.cmake script with Android NDK r8c!

What do you see instead?
A couple of warnings (but they are all the same):
CMake Warning at /home/jumio/workspace/ocr/scripts/android.toolchain.cmake:318 
(message):
  Could not uniquely determine machine name for compiler from
  /opt/build-tools/android-ndk-r8c/toolchains/mipsel-linux-android-clang3.1/prebuilt/linux-x86.
Call Stack (most recent call first):
  /home/jumio/workspace/ocr/scripts/android.toolchain.cmake:481 (__DETECT_TOOLCHAIN_MACHINE_NAME)
  /home/jumio/workspace/ocr/build/CMakeFiles/CMakeSystem.cmake:1 (INCLUDE)
  CMakeLists.txt:3 (PROJECT)

What version of the product are you using? On what operating system?
latest, on Ubuntu 10.10
