Acutally that's how we are doing it ...

Install the cross-compiled stuff on your local disc e.g. into a 
"transfer" directory. Then copy it to the target.
On the target 'cp -Rfa <transfer-dir>/* /' should do it if the basic 
directory structure fits to your rootFS.

There is IMHO no standardized variable available. Just look into the 
configure script how the variable is named and if it is actually 
available at all.

  ... you may supply a custom install prefix directory to configure.
