[doc] Update install.texi for Solaris 2, IRIX, Tru64 UNIX


I've just reviewed install.texi for my platforms and found it mostly
accurate.  A few minor changes are desirable for the 4.6 release, but
also apply to mainline since the file is identical there:

* Update recommendations to binutils 2.21 since this is what I've been
  testing.

* Remove download URL for Sun Studio compilers since AFAIK we're not
  supposed to link to non-free software.

Tested with make doc/gccinstall.info doc/gccinstall.pdf
`pwd`/HTML/gcc-4.7.0/gccinstall/index.html (the latter seems a bit
contorted to regen just a single html document) and visually inspection.

Ok for mainline and 4.6 branch?
