Summary0015766: Fails to infer CMAKE_ASM_COMPILER with CC='ccache gcc'
DescriptionFor CMAKE_C_COMPILER, "gcc" is fed to the first in the argument.
In contrast, "gcc" disappears for CMAKE_ASM_COMPILER.

Of course, it works if ASM is explicitly specified without ccache.
Steps To Reproduceproject(Test C ASM)
cmake_minimum_required(VERSION 2.8.12.2)
add_executable(Test foo.c bar.S)

# CC=ccache\ gcc cmake .

# make
[ 66%] Building ASM object CMakeFiles/Test.dir/bar.S.o
/usr/bin/ccache -o CMakeFiles/Test.dir/bar.S.o -c /home/tnakamura/fio/ninja/xxx/bar.S
/usr/bin/ccache: invalid option -- 'o'

CMake 3.4 will have a new CMAKE_LANG_COMPILER_LAUNCHER setting that will be the preferred way to use ccache. Does that work for this case?
