You have explained it well enough, I think, and the
solution I explained above works fine. If it doesn't
work for you, then you did it wrong. The solution
written at the URL you mentioned is unnecessarily
complicated.
$ echo $BINMAKE
`if [ -x /usr/obj/usr/src/make.i386/make ]; then echo /usr/obj/usr/src/make.i386/make; else echo make; fi` -m /usr/src/share/mk
$ newvariable=`eval echo $BINMAKE`
$ echo $newvariable
make -m /usr/src/share/mk
$
