[CMake] cmake + ninja + CMAKE_TOOLCHAIN_FILE fails

[Guilherme]

Hi!

When using 'cmake .. -DCMAKE_TOOLCHAIN_FILE=../cmake/m3.cmake' with
the makefile generator this works prefectly but when using it with
'cmake -GNinja .. -DCMAKE_TOOLCHAIN_FILE=../cmake/m3.cmake' it fails
with the following message:

cmake -GNinja -DCMAKE_TOOLCHAIN_FILE=../cmake/m3.cmake ../

-- The C compiler identification is GNU 4.6.3
-- Check for working C compiler using: Ninja
-- Check for working C compiler using: Ninja -- broken
CMake Error at 
/usr/local/share/cmake-2.8/Modules/CMakeTestCCompiler.cmake:61
(message):
   The C compiler "/srv/scratch/ARM_EABI/bin/arm-none-eabi-gcc" is not 
able to
   compile a simple test program.

   It fails with the following output:

This is the m3.cmake file:

set(COMMON_FLAGS "-ffunction-sections -fdata-sections -fno-builtin

set(CMAKE_C_FLAGS " ${COMMON_FLAGS}")
set(CMAKE_CXX_FLAGS "${COMMON_FLAGS} -ffunction-sections

I already posted this in the ninja mailing list and they told me to come 
here.
