2951	Add support for amd64-solaris2 platform	kgardas		"Hello,

it would be nice if GHC build correctly detects if it's running on amd64 platform or plain old i386 platform. The problem is that current config.guess returns in both cases i386-pc-solaris2.* string. Certainly there is a possibility to use `isainfo -n` to test for application supported instruction set, see:
{{{
karel@silence:~/vcs/ghc$ ./config.guess 
i386-pc-solaris2.11
karel@silence:~/vcs/ghc$ isainfo -n
amd64
karel@silence:~/vcs/ghc$ 
}}}

I'm just not sure if hacking configure.ac's code below
{{{
i[[3456]]86-*-solaris2*)
        HostPlatform=i386-unknown-solaris2 # hack again
        TargetPlatform=i386-unknown-solaris2
        BuildPlatform=i386-unknown-solaris2
        HostPlatform_CPP='i386_unknown_solaris2'
        HostArch_CPP='i386'
        HostVendor_CPP='unknown'
        HostOS_CPP='solaris2'
        ;;
}}}
and changing HostArch_CPP from 'i386' to 'x86_64' would be enough for the change.
