Make the Building Guide almost valid DocBook XML V4.2 (to get the real thing,
simply add an XML prolog and change "artheader" to "articleinfo"). Things that
had to be changed:
* XML tags are case-sensitive, so lowercase must be used for tags/attributes
* Make "xref" an empty element.
* "constant" is not allowed within "filename"
* Move "indexterm" to a valid place.
* Change some "&" to "&"
* The "_" character in titles makes some trouble in the TeX backend => avoid it
