How about sth like

#+begin_src makefile
something:
	@ echo "Doing something"

guix-something:
	guix shell coreutils -- $(MAKE) something

.PHONY: something guix-something
#+end_src

Assuming you did put the above under /tmp you can try it out like this

#+begin_example
/tmp$ make something
Doing something
/tmp$ make guix-something 
guix shell coreutils -- make something
make[1]: Entering directory '/tmp'
Doing something
make[1]: Leaving directory '/tmp'
#+end_example

This is great for phony targets (i.e. ones that are not intended to
produce a file with the same name as the target). You're also not
forbidden from making `guix-` variants for non-phony targets the same
way. Although then the `guix-` variant will end up being phony anyway
¯\_(ツ)_/¯
