	If there even is such a standard tnan proposed "fix"
does'nt break it - cause before this fix all other '-' options
(apart from -j<n>) were parsed independently of their position
on the command line (before or after some variable definitions).
So, such a (hipothetical) standard can only be established by
some Makefile writing discipline and we can see that f.e. in
current /usr/src/Makefile this (hipothetical) discipline is not
followed ;-)

	Here is an example of command(s) generated for
"make buildworld" in current (long lines wrapped) :
