Revert "Revert "Makefile: allow for different compilation methods""

This reverts commit 510f6464b06932406051fd0983586f6c1680e098.
Makefile: implement different compilation methods, rename _COMPILE_ to ORGCM

* default.mk, targets.mk, lisp/Makefile: Rename _COMPILE_ to ORGCM.

* default.mk: Define ORGCM=dirall, show other possible values as
  comments

* targets.mk: Implement target `single´, temporarily set
  ORGCM (overriding configuration).  Show newly introduced
  configuration variables with `check-*´.

* lisp/Makefile: Implement dispatch for compile based on ORGCM.
  Output header that contains the target for easier debugging.

* Makefile: Document target `single´.
Makefile: fix some errors

* targets.mk: Repair .PHONY target.  Correctly group ORed parameters
  in find calls.  Introduce $(CLEANDIRS) and use variable instead of
  literals.  Have a command succeed at the end of `config-*´ so that
  no spurious warning is given by make.
server.mk: implement ELPA

* UTILITIES/server.mk: Add ELPA archive generation.
Makefile: add link to Worg to `make help´

* Makefile: Add link to documentation for the build system on Worg.
