Building 32-bit binaries on Solaris

On my SPARC test system, running configure using '--with-target-bits=32' 
did the job, and created a configuration called 
'solaris-sparc-normal-server-release' right beside my existing 
'solaris-sparcv9-normal-server-release':

cd <top of tree>

sh ./configure \
     --with-tools-dir=/opt/devtools/sparc/SUNWspro/sunstudio12.1/bin \
     --with-cups=/opt/devtools/share/cups \
     --with-target-bits=32
[... snip ...]
Configuration summary:
* Debug level:    release
* JDK variant:    normal
* JVM variants:   server
* OpenJDK target: OS: solaris, CPU architecture: sparc, address length: 32


The build ran in 33 minutes (this was on a SPARC LDOM with 4CPUs granted 
to it, so nothing special to write home about):


% cd build/solaris-sparc-normal-server-release
% gmake all

Hope this helps-
