I'm not sure what you mean by "all my subsequent rules".

You can do it by simply setting the make variable PATH.  Read the
section of the make manual "Variables from the Environment".

If you want to be explicit about it you can use "export PATH", but this
is not strictly necessary if there was a PATH variable in make's
environment when it was started (and really, isn't there always?)

        PATH := /my/special/bin:$(PATH)
        all: ; @echo '$(PATH)'


However, this will take effect for ALL rules in the makefile not just
the "subsequent rules".  There's no way to do this with a single
invocation such that it takes effect for some rules but not others.
