First, when in the world is PATH not exported?  I've never run across an
environment where PATH wasn't exported.

Anyway.  When you say "execute a shell script", do you mean using the
$(shell ...) function, or do you mean a normal command script make
invokes to update a rule?

If the latter, then exporting PATH in your makefile will definitely
work.  If the former, then it won't be enough, because variables that
are marked exported inside the makefile are only exported to command
scripts, not $(shell ...) functions.

To work around this you can use:

        $(shell PATH="$(PATH)" <command>)
