 If I don't specify $target_alias then it defaults to $target.  As a
result $tooldir (aka $exec_prefix/$target_alias) will be set incorrectly
for native tools.  What's the point in pretending to build cross-tools
when both the host and the target are the same? 

 Also I believe it is more consistent to select the configuration by
argument values and not their presence -- this way you may specify a
template for passing $build_alias, $host_alias and $target_alias in the
same manner, regardless of actual values, with no special cases. 

 Hmm, after a bit of thinking, I believe the script should even check if
$target equals $host.  After all that's a native configuration as well
even if $host_alias and $target_alias differ.
