PATCH: Improve Solaris installation documenation

[Mark Mitchell <mark at codesourcery dot com>]

The GCC Steering Committee has decided not to require GNU Make for
building GCC 3.0.  However, the SC has also decided that GCC 3.0 may
not build with GNU Make.  In other words, other implementations of
make may or may not work, but we won't try to keep people from using
them.  (For the record, I didn't agree, but that's neither here nor
there, really.)

So, if we know of platforms where non-GNU Make does not work, they
should be noted in install.texi. 

Here's a patch for the Solaris version.  I also cleaned up some 
information about -fsquangle that is no longer valid, given that this
option no longer exists.
