But then I fail to see the point of the macro.

The installation instructions for the supercomputer will then have to be 
"use configure --host .... for most configure-script-using programs, but 
for programs X, Y, and Z (versions higher than xxx.xxx) you can just use 
configure".   But then users have two cases to remember instead of one.

If you have to learn to use --host for installing some applications, you 
might as well do this for all of them.
