The GNU autotools book has a whole chapter about this, too much for me
to parse and summarise here quickly. There's probably a section in info
autoconf too. The most useful thing is it sets a shell variable called
cross_compiling ("yes" or "no"). The book also says you need to watch
out for AC_TRY_RUN and AC_CHECK_SIZEOF, and some others that look a bit
obscure.
