IOStreams shouldn't refer to boost_zlib. It should use /zlib//zlib
conditioned only on NO_ZLIB/NO_COMPRESSION. I'm not certain that
this will work in all cases, right now. It should, correctly, do
nothing when there is no zlib at all, but I'm not sure what it
will do for pre-built libraries
Actually, I take that back. I never considered the possibility
of users referring to targets other than /zlib//zlib. If I
make /zlib//<whatever-was-given-as-build-name> a visible
target, I'll be able to fix some long standing issues
that I've been ignoring, i.e. what happens when multiple
projects specify different build-names. For now, however,

No. is-default is true. It will arbitrarily select
the first one to be called, which is fine since all
the uses inside Boost should be identical.
