[CMake] Assembler flag support

Yes, I tried that. Just for reference, my plattform file looks like this:

---

Without the -cpu option, the assembler can't assemble a file. So i tried 
to set the flags within the INIT-Variables, but when i run make (I use 
MSYS Makefiles), the assembler is called without the -cpu command line 
option (snipped of the output of make VERBOSE=1):

cd /C/Projekte/Software/Gen/Src/Processor && 
/C/Projekte/Tools/Softune/V30/bin/FASM907S.EXE 
-I/C/Projekte/Software/Src/Generic -I/C/Projekte/Software/Src/Processor
-I/C/Projekte/Software/Src/Main   -o 
CMakeFiles/lib_processor.dir/MB90340.s.o 
/C/Projekte/Software/Src/Processor/MB90340.s

Cheers,
Matthias.
