Once again, the standard way of invoking a makefile is to change the
current directory and call make, which is what GNU make does with make
-C directory. Therefore $(shell pwd) will work (it's a GNU extension,
BTW, since the online BSD make man page doesn't document it).

Option -f is not meant for running a makefile in a different
directory, but for selecting a makefile for the current directory,
when e.g. you need to distinguish between Windows and Unix, between
BSD make and GNU make, etc.

I saw that. This doesn't help when asdf is in the source-registry,
though (which is the recommended way of having an asdf upgrade: "just"
having its source in the source-registry, e.g. in ~/common-lisp/asdf/)
