Compiler version can't be determined with latest NDK

[GoogleCodeExporter]

What steps will reproduce the problem?

I use a standalone ndk, but I think it will be a problem with a normal ndk too. 
If I try to use android-cmake, I get errors that no compiler toolchain can be 
determined

What is the expected output? What do you see instead?

It should find the toolchain.

What version of the product are you using? On what operating system?

- max osx 10.7.5
- cmake 2.8.10.2
- android-cmake -> can't find a version number, but I'm quite sure it's the 
latest one.
- android ndk r8d

Please provide any additional information below.

The problem seems to be that the version number of the gcc version in the 
latest NDK is 4.7. The regular expression that tries to extract the gcc version 
expects 3 components (like 4.2.1)

Replacing line 467 

  string( REGEX MATCH "[0-9]+.[0-9]+.[0-9]+" __availableToolchainCompilerVersions "${__availableToolchainCompilerVersions}" )

with

  string( REGEX MATCH "[0-9]+.[0-9]+(.[0-9]+)?" __availableToolchainCompilerVersions "${__availableToolchainCompilerVersions}" )

fixes the problem for me.

You can find up-to-date version of this project on my github fork: 
https://github.com/taka-no-me/android-cmake This problem should be already 
fixed.
