This tests passing CFLAGS with spaces to an application and also that even if the CFLAGS are defined after Makefile.include, they trigger a rebuild when modified. This includes an example how to pass macros with spaces to a docker build. The test as both an automated part for the CFLAGS with spaces, and a manual part for the two other features.
