DJ has objections to the change, unfortunately.  Personally, I don't
have any problem with this change: it will only affect the ./configure
case, that has long been recommended against, and even then, will only
make a difference for someone for whom the change would actually make
some difference, e.g., not someone who's only half-mindlessly building
and installing the package.  If you need to enter some sub-package
build-for-host directory, you'll probably be able to figure out what's
the right thing to do.  If you have scripts to automate some of these
steps, then you probably do this often enough that you probably don't
want to pollute your source tree with builds and already follow the
recommended procedure to build out of the source tree.  So, I'd
approve this change if it wasn't for DJ's objection.

DJ, given my arguments above, would you be willing to withdraw your
objection?

Any comments for binutils or GDB folks?  Does anyone object to moving
the directories in which we build tools for the host to a host subdir
when srcdir=.?
