Summary: Add 64-bit Solaris 9 build instructions to README

Initial Comment:
It would be helpful to add the correct 64-bit Solaris 9
build flags to the README file.  I'm still working
through problems with Solaris 10, but these flags
seemed to work well for Solaris 9.  One could replace
the "-native64" with "-generic64" for maximum binary
compatibility if necessary: (csh syntax env commands below)
setenv CC cc
setenv CXX CC
setenv BASECFLAGS "-native -xarch=native64 -mt -xO3"
setenv LDFLAGS "-xarch=native64"
./configure --without-cxx

I believe there is no single set of "correct" options. E.g.
why is it necessary to pass -xO3? I'm sure it will build
fine without that; also, -O is documented to expand to -xO3.
Likewise, why -mt? configure should figure out the necessary
libraries itself, and -mt links with -lthread, when it
really should link with -lpthread.

-native is documented as synonym for -xtarget=native. This
in turn isn't documented much, but if it included
-xarch=native, I don't understand why you want that: it is
documented as "The compiler chooses the appropriate setting
for producing 32-bit binaries".

IOW, I think that setting CC to "cc -xarch=native64" should
be enough. Unfortunately, I don't have a Sun compiler on
Solaris, so I personally use gcc instead.
