Summary:                    GHS Multi Generator: COPY_FILE in try_compile does
not work
Description: 
try_compile COPY_FILE: The GHS MULTI Compiler compiles+links the executable to
"targetname.as", but the CMake Generator currently looks for "targetname"
(without extension). As a folder with such a name exists in the build directory
COPY_FILE copies the folder instead of the built executable and the try_compile
execution does not fail.



Steps to Reproduce: 
Create a simple CMakeLists.txt like this:

try_compile(
	result
	"${CMAKE_BINARY_DIR}/CMakeFiles/CMakeTmp" 
	"${CMAKE_SOURCE_DIR}/test.c" 
	COPY_FILE "${CMAKE_BINARY_DIR}/test_executable" 
)
message(STATUS "result of try_compile: " ${result})


Create a simple test program as "test.c":

int main(int argc, char *argv[])
{
    return 0;
}

Run CMake using GHS MULTI Generator (ARM Integrity).

Actual result:
try_compile succeeds and a empty folder "test_executable" is created in the
build directory

Expected result:
try_compile succeeds and the built executable "test_executable" is located in
the build directory

Additional Information: 
I've tried setting
set("CMAKE_EXECUTABLE_SUFFIX", ".as")
manually at various locations but it didn't work. Either it wasn't set at all or
overwritten; I don't know.
