    bfd: Re-enable 64-bit support for 32-bit Solaris targets
    
    One of the recent Solaris patches removed want64=true from the 32-bit
    Solaris targets.  This breaks GCC bootstrap: unlike Linux, GCC on
    Solaris is always biarch, both in 32-bit-default and 64-bit-default
    configurations, so the 64-bit multilib fails to build.
    
    This patch undoes this incompatible change.
    
    Tested on i386-pc-solaris2.11 and sparc-sun-solaris2.11.

            * config.bfd <i[3-7]86-*-solaris2*> (want64): Add.
            <sparc-*-solaris2*>: Likewise.
