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 configure.ac 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 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.
