[doc] Update install.texi for Solaris 12 rename

[Rainer Orth <ro at CeBiTec dot Uni-Bielefeld dot DE>]

There's one Solaris 12 reference in install.texi that also needs
adapting for the Solaris 12 -> 11.4 change.  However, instead of simply
updating it I chose to update the relevant sections for current binutils
versions.

Tested with make doc/gccinstall.info doc/gccinstall.pdf and visually
inspecting the pdf.  Will install on mainline shortly.  I've no
intentions of backporting to the gcc-7 and gcc-6 branches, though:
unless something critical comes up, I usually keep branches as is.
