   Split rules for .spec files as input files vs import libraries. .spec files can now be specified independently as <file>s (to generate and compile a .stubs.c file) and <importlibrary> (to generate and compile a .spec.def file)
   .spec files are now specified in <importlibrary>s directly (instead of pointing to the non-existing, generated .spec.def file. Whose idea was that? sounds like the doing of Arch Blackmann)
   Allow multiple modules to share a single .spec file without using <importlibrary base="...">
   Allow static libraries to use .spec files in <importlibrary>
   Emit comments in makefile.auto so rules can be traced back to the code that generated them

   .def -> .spec

<<hundreds of rbuild files>>
   Remove <file> entry for spec file if there are no stubs to compile
   .spec.def -> .spec in <importlibrary> entries

Soon: making all keyboard layouts use a single .spec file
