HowToCrossCompile was outdated and generating too much traffic on the mailing
list with similar queries. This change helps offset most of the problems that

* Making references to Debian's multiarch for target libraries
* Expanding -DCMAKE_CXX_FLAGS for both GCC and Clang
* Some formatting and clarifications in the text
