Yup, it's all wrong. Libtool shouldn't care about the target, only
about the host.

When you use a cross compiler, it means you're building for a
different *host*, not target. The host is the platform on which the
built program is going to run. Build is the platform on which you're
building the program, and target is the platform for which the
compiler being built should generate code. So libtool is only
concerned with host, not target. I wonder how I let this one pass :-(

When cross compiling to Windows, Windows is the `host'. `target' only
makes sense for the toolchain, and it should never affect the way
libraries are created, because they'll never run on a target platform;
they'll only be created in the build platform and run on the host platform.

We'll have to review this code and remove all references to target,
and use host wherever we currently refer to target.
