or

MAKE_ARGS= -EMANPREFIX
MAKE_ENV= MANPREFIX=/man

I tested this with:

[crees at zeus]~% cat Makefile
HELLO=  "hello, world"
all:
        @echo ${HELLO}
[crees at zeus]~% make
hello, world
[crees at zeus]~% env HELLO=hello make
hello, world
[crees at zeus]~% env HELLO=hello make -EHELLO
hello
[crees at zeus]~%

Try it out!

Though I still think the usual response is to use REINPLACE_CMD on the Makefile.

NB gmake doesn't have the -E flag, but the -e flag sets environment
precedence on all variables. Sounds risky!
