Oh, but it is!
That's the beauty of autotools... srcdir and builddir can be different,
and you can have as many builddirs as you want:
(the libs are written to the builddir, not the srcdir)

$ mkdir /tmp/single ; cd /tmp/single
$ /cdrom/src/opende/configure --prefix=$HOME/ode-single
$ make install

$ mkdir /tmp/double ; cd /tmp/double
$ /cdrom/src/opende/configure --prefix=$HOME/ode-double --enable-double-precision
$ make install

And there you have it: two trees, using the single source tree,
and not a single file gets written to the source tree using the builds.
