cmake: add control over inline source code disassembly

By default, the generated disassembly file (i.e: the .lst
file) also contains inline source code. This has the
potential to become problematic when attempting to compare
the generated .lst files accross platforms since they may
differ for various reasons. As such, add the option to
control whether the disassembly file should contain inline
source code or not.
