While debugging an issue with our online documentation at 
https://gcc.gnu.org/onlinedocs (which I traced down to a bug 
with the old version of makeinfo on that host) I noticed WWWBASE 
was hardcoded without a way to override without changing the script.

That's obviously not too helpful when running on a local system,
and I addressed it by the patch below, also adding a comment on
the way.

Tested on my notebook (modulo jit) and gcc.gnu.org, and committed.

	* update_web_docs_svn: Remove a reference to GCC 3.1.  Describe
	settings to tweak if running on a host different from gcc.gnu.org.
	(WWWBASE): Allow override via the environment.  Also check for
	existance.
