In the autotools world these are the --build and --host options
respectively. There's also --target which is used when you're building a
compiler.

Looking back through the thread, I don't see an explanation of why you
need to figure out the build system's triplet yourself. Configure
scripts will typically come with a copy of config.guess and figure it
out on their own.

It should also be noted that build systems that handle cross compiling
correctly are actually not too common (even among the ones that use
autotools).
