Summary:                    CMake incorrectly passes C/CXX flags to assembler
Description: 
When building mixed C/CXX/ASM projects, CMake incorrectly passes C/CXX compiler
options to assembler. On some platform (standard X86 GNU compilers), this is not
an issue, but in my case where I cross-compile on X86 for ARM target, the
assembler refuses to compile due to invalid options as follows:

[user at host temp]$ make
Scanning dependencies of target asmbug
[ 50%] Building CXX object CMakeFiles/asmbug.dir/main.cpp.obj
[100%] Building ASM object CMakeFiles/asmbug.dir/asmfunction.S.obj
/usr/local/embedded-cross-compilers/arm-eabi-as: unrecognized option '-O3'
make[2]: *** [CMakeFiles/asmbug.dir/asmfunction.S.obj] Error 1
make[1]: *** [CMakeFiles/asmbug.dir/all] Error 2
make: *** [all] Error 2


Steps to Reproduce: 
Run CMake on the attached example project. This requires an arm cross
compilation toolchain to be installed.
