NRK 197afce935 introduce config.mk
this moves all the build variables intended to be modified by the user
over to `config.mk` similar to other suckless software.

also move CPPFLAGS down below for cosmetic purposes.

Bert Münnich 5155d52ab1 Much more portable Makefile
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]

Bert Münnich a46006f527 Support out-of-source builds
Fixes issue #167. Long after closing this issue (kind of wontfix) we have switched to
GNU make and can thus use its features like VPATH.
