That port wouldn't be called x-box, because dash separates the different 
parts of a target tripplet (which is why the platform by the marketing 
name of AMD64 is spelled x86_64 instead x86-64).

Your wish is my command.  Patch proposal below for comments

This patch accomplishes the goal to get rid of asterisks in @anchor
names by

 - replacing components of a target triplet which read "*" by "x",
 - and omiting trailing asterisks from all other components.

Tested by running doc/install.texi2html and selecting every single
link in the directory of specific.html.

2005-04-14  Gerald Pfeifer  <gerald@pfeifer.com>

	* doc/install.texi: Avoid using asterisks in @anchor names.
	Remove i?86-*-esix from platform directory.
	Remove powerpc-*-eabiaix from platform directory.
