Cross-compiling
========================================================================
Cross-compilation requires at least two flags to `configure':
* `--host=OS', where OS is something like `i386-gnu-linux'
* `--enable-racket=RACKET', where RACKET is a path to a Racket
executable for the version being compiled that runs on the build
(i.e., you must compile on the build machine to cross-compile)
The `--enable-racket' flag is needed because building and installing
Racket requires running (an intermediate version of) Racket.
