History
harti ce8ae127b1 Put variable assignments from the command line into the MAKEFLAGS 
variable as required by POSIX. This causes such variables to be
pushed into all sub-makes called by the make (except when the MAKEFLAGS
variable is explicitely changed in the sub-make's environment).
This makes them also mostly un-overrideable in sub-makes except on the
sub-make's command line. Therefor specifying 'make CC=icc' will cause
icc to be used as C compiler in all sub-makes no matter what the Makefiles
itself try to do to the CC variable.

This patch also corrects the handling of the MFLAGS variable. MFLAGS
contains all the command line flags but not the command line variable
assignments. The evaluation of the .MFLAGS or .MAKEFLAGS target now
changes both MFLAGS and MAKEFLAGS (they used to change MAKEFLAGS only).
Makefiles can use MFLAGS for their own purposes given that they do not
except MFLAGS to be undefined at the beginning and that they don't evaluate
.MFLAGS or .MAKEFLAGS. MFLAGS should be removed for POSIX compliance,
but it is unfortunately heavily used by the X makefiles.

This has been extensively tested by port builds (thanks to portmgr), new
worlds and kernels.
