[doc] Remove Tru64 UNIX and IRIX references in install.texi

[doc] Remove Tru64 UNIX and IRIX references in install.texi

[Rainer Orth]

[-- Attachment #1: Type: text/plain, Size: 760 bytes --]

I happened to notice that install.texi still contains references to the
Tru64 UNIX and IRIX ports I've removed in GCC 4.8.  I believe it's time
now to get rid of those completely.

Tested with make doc/gccinstall.info and doc/gccinstall.pdf.  Ok for
mainline?  This falls under my prior maintainership, I guess, but
think it's best to get a second opinion.

OK.  THere's probably a ton of ancient host/build issues that should
just get removed.

Thanks for catching this.  In general I think we should document only 
GCC's current behavior and not mention removed functionality except in 
release notes.  I think this whole document needs review for that sort 
of thing, but every bit helps.

Can you fix this nit while you're in there?

probably, but it's hard for anyone but the respective maintainers to
know/check.  I've tried to keep things clean for my ports at least when
obsoleting some older OS version or the port as a whole.

this example shows that you're probably right: my thinking a the time
probably was that it's easier to find the obsoletion info in the
(current) install.texi than checking through various older changes
documents, but obviously I missed the time to finally remove it before now.

Sure, done.

Thanks.
