The same way that you implement portable build actions. Most of what
bjam does is invoke system calls, after all.

Unfortunately the structure of bjam doesn't currently allow dependencies
to be calculated after any build steps, so we could only arrange to
build files that were already on the client machine before bjam was invoked.

What we actually need is a portable popen4 implementation built into the
bjam core. Having looked at the one in Python, I think it would be
pretty easy to transplant.
