[Swan-dev] New top level directory mk/ for make include files

[Andrew Cagney]

Put simply, I'm giving in. I'm planning on moving the top-level make
include file that I added:

  Makefile.dirs

to the subdirectory mk/, and then renaming it:

  mk/dirs.mk

each change has its own motivation:

  - I think the top-level directory is getting too cluttered, and is
only going to get worse (I've got the files depends.mk and subdirs.mk
kicking up sand in my sandbox)

  - emacs recognizes the .mk suffix and configures things accordingly

the existing common Makefiles should, eventually, follow.
