So I'm not *entirely* sure if this caused it, but I noticed that doing

	make -C linux M=/path/to/extmod/ modules_install

stopped working.

This is because here:
> -extmod_prefix = $(if $(KBUILD_EXTMOD),$(KBUILD_EXTMOD)/)
> +export extmod_prefix = $(if $(KBUILD_EXTMOD),$(KBUILD_EXTMOD)/)

(as before, of course) another trailing / is added to the M= argument,
and then

> +modules := $(patsubst $(extmod_prefix)%, $(dst)/%, $(modules))

this patsubst turns out to do nothing. So $(modules) contains the
original paths where the modules were compiled, and consequently nothing


	make -C linux M=/path/to/extmod modules_install

actually works.

Obviously I can work around it, but it hardly seems intentional?
