get binbuild working again, and zap the BinaryDistribution layout

at the same time

a few days ago the configure syntax for specifying a layout was fixed
in binbuild.sh, but the layout was broken...  it turns out that we
don't need the layout

with Apache 1.3, a separate layout for binary builds was necessary
in order to install under any prefix specified by the user

with Apache 2.0, that works without any special tricks so the
BinaryDistribution layout is no longer necessary
