Teach the Makefile generators to escape '#' characters on the right hand side of variable assignments in flags.make. This is needed for flags like '-Wno-error=#warnings'. Otherwise the make tool treats them as comments and leaves them out of the _FLAGS variable value. Add a case to the CompileOptions test covering '#' in a COMPILE_OPTIONS value, at least on compilers where it is known to be supported.
