I don't know much about Solaris.
If there is a IPv6 package for Solaris 2.7, you should install it
befor building firefox or mozilla.
There is a official release package for Solaris 2.7, so I guest there
is a IPv6 package for Solaris 2.7.

http://ftp.mozilla.org/pub/mozilla.org/mozilla/releases/mozilla1.6/contrib/mozilla-sparc-sun-solaris2.8-1.6.tar.gz

IPv6 package is required to build Mozilla but Mozilla will probe IPv6
protocl stack and use it if it is avaiable.
So you don't need IPv6 package to run Mozilla.

BTW, there are other requirements to run mozilla on Solaris.
Have you installed them?
