I don't quite know what you mean, but there's no good way to change an
environment variable without also changing the make variable of the same
name.
Your only alternative is to do something like:
foo:
MYVAR=somevalue <command>
That is, set it in the commandline itself.
If you want to set it for all subprocesses of make, then you must set
the variable in the makefile (changing the value of that variable in
make) and export it:
MYVAR = somevalue
export MYVAR
