This decision was made to reduce the complexity of using .include whilst
juggling with tools/scaninc and tools/preproc:
- tools/scaninc doesn't apply the proper search rules for .include (it
  assumes #include behavior). In particular, it doesn't consider paths
  starting from $PWD, and doesn't scan the included files as a result.
- .include had to be processed before #include by preproc in many cases,
  as code was being included that had to be preprocessed by CPP (think
  of #define). This contradicts standard GCC behavior.

To make include paths consistent across the asm/ data/ and src/
directories, the following files were moved:
- constants/ → include/asm/constants/
- asm/macros/ → include/asm/macros/
- asm/macros.inc → include/asm/macros.inc
- include/macros/m4a.inc → include/asm/macros/m4a.inc

As part of the necessary changes for this to work, the scaninc method in
the makefile was improved to generate .d files that don't choke when
files are missing.
