The following patch updates install.texi for Solaris, and applies
equally to the 4.7 branch and mainline.

Tested with make doc/gccinstall.info doc/gccinstall.pdf, ok for mainline
and 4.7 branch?

+Sun does not ship a C compiler with Solaris 2 before Solaris 10, though
+you can download the Sun Studio compilers for free.  In Solaris 10 and
+11, GCC 3.4.3 is available in @command{/usr/sfw/bin/gcc}.  Solaris 11
+also provides GCC 4.5.2 in @command{/usr/gcc/4.5/bin/gcc}.  Alternatively,

I see Richi has approved, just wonder whether "as @command" would
be more appropriate than "in @command", twice?
