So, all packages that you might potentially want to cross-compile onto supercomputers, from guile to libpng to fftw, are supposed to add this macro to their files?

Of course not. Many applications doesn't mean all applications.

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 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.
