possible variations for remote building?

[Robert P. J. Day]

  before i get into detail, what are the acceptable variations for
building busybox in a directory separate from the source directory?
(i can see how it's *supposed* to work in the top-level Makefile but a
number of tests i've run seem to show that remote building is broken.)

  a pointer to a URL covering this would work just fine, thanks.
