Commit 7b17bafc5d7948aff3059e058ada80ad1fc50500 by Davide Viti has a detailed explanation of some unusual techniques used for building host-cmake and (target-)cmake. This is useful information for whoever starts hacking on it, so copy it in the makefile, where it will be easily noticed. Also remove the sentence about host-cmake having a runtime dependency on host-pkgconfig (not true anymore: it's the specific cmake-packages that depend on it) and fix typos.
