Added cross compiler and stack protector variable to Makefile
...
If using another tool chain to compile everything, like on the Intel SCC
or OS X, there is only one variable in the Makefile to change the cross compiler prefix.
Furthermore, there is another variable to remove the -fno-stack-protector setting, which is important for compiling on the SCC.
Adapted the documentation to this, too.
