Fix "make html" and "make pdf" for libgloss

["Joseph S. Myers" <joseph at codesourcery dot com>]

This patch adds support for the "html" and "pdf" targets to libgloss, to 
build documentation in those formats, and fixes some problems with the 
libgloss manual that stopped the PDF build from working (subsections 
should not be directly below chapters).  OK to commit?

2009-06-19  Joseph Myers  <joseph@codesourcery.com>

	* Makefile.in (html, pdf): New.
	* doc/Makefile.in (html, pdf, porting.pdf, porting.html): New.
	* doc/porting.texi: Fix section structure.
