James gave me an incredibly useful advice: Interpose execution
and rewrite arguments. For example to rewrite arguments to cc
and CC you can write this (taken from
   http://gar.svn.sourceforge.net/viewvc/gar/csw/mgar/pkg/flac/trunk/Makefile

> include gar/category.mk
>
> CC := $(abspath ./bin/cc)
> CXX := $(abspath ./bin/CC)

and then have heavy hacking (here, includes to relative pathes
are reordered to be before include to absolute pathes):

You could poke around stuff for "ld" also, of course...
