  Log:
  Introduce a new pseudo-target .EXPORTVAR which allows to put a
  make macro into the environment of programs executed by make. This
  has approximately the same function as gmake's export directive.
  The form of a pseudo target was deliberately choosen to minimize work
  for POSIX compatibility (Makefiles are not allowed to use any targets
  starting with a dot and consisting only of uppercase letters except those
  specified in the standard when they want POSIX compatible behaviour, so
  such a Makefile can never contain .EXPORTVAR.)
  Change the handling of macros coming from the environment: instead
  of asking the environment for each variable we could not find otherwise
  put all the environment variables in a special variable environment just
  at start up.
  
  This has been tested on the ports cluster by kris.
