No specific reason.  Initially I wrote without the container option ’-C’
or --pure, so really recursive.  But then I checked if it also worked
with the container option ’-C’ and let the old $(MAKE) invocation.

In case reader is not convinced, here $(MAKE) does not refer to the same
’make’:

--8<---------------cut here---------------start------------->8---
$ cat Makefile
stuff:
        which make

guixy:
        @guix shell -C which make -- $(MAKE) stuff

$ which make
/usr/bin/make

$ make stuff
which make
/usr/bin/make

$ make guixy
which make
/gnu/store/dp8bar2xgzwz1yfm9lcafqn3vhs2cjqc-profile/bin/make
--8<---------------cut here---------------end--------------->8---
