Add libgloss install-pdf and install-html targets.

The toplevel makefile used by binutils/gcc/newlib/etc has install-pdf and
install-html targets, but they fail because libgloss doesn't support them.
Tested with an arm-eabi combined tree build and install, and verifying that
the install-pdf and install-html targets now work, and that the pdf and html
doc files are now in the install tree.

	libgloss/
	* Makefile.in (install-html, install-pdf): New.
	* doc/Makefile.in (htmldir, pdfdir): New.
	(porting.ps): Delete white space on blank line.
	(install-pdf, install-html): New.
