Compiler version can't be determined with latest NDK #15
Description
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.
