The config.mk file is now optional and only needs to be created if one wants to
persistently overwrite default macro values.
Features used in the Makefile that are not yet in the POSIX standard:
- Advanced macro assignment operators '+=' and '?=' [1]
- Special target .PHONY [2]
- Pattern rules [3]; only needed when $srcdir != '.'. For every pattern rule
there is an inference rule with the same effect. Hopefully, the inference
rules get picked up by make programs not supporting pattern rules.
- Silently including multiple possibly not exisiting files [4] [5]
