That's a procedural question: do we want to accept environment settings
only when running configure, or do we also want to honor environment or
make command line settings when make is invoked. IOW, it is ok if

export OPT=-O6
./configure
make

works. But what about

./configure
export OPT=-O6
make

or

./configure
make OPT=-O6

All three can be only supported for environment variables that are never
explicitly set in Makefile, be it explicitly in Makefile.pre.in, or
implicitly through configure.

No. I thought you were talking about extra args, such as -fbrett-cannon.
But now you seem to be talking about arguments that replace the ones
that configure comes up with. Either of these might be reasonable, but
they require different treatment. Replacing configure results is
possible already
