This is a regression: it worked just fine with earlier 1.7.x releases.

This is different: neither the wrapper nor assembly are executed in the
builddir; they are just created there and installed into different
locations.

It's definitely a bug (or two) somewhere:

* "install foo" correctly installs 'foo' but the presence of foo.exe
apparently fools something to add the .exe.

* the .exe is being added when the file is clearly not a PE executable,
nor a link thereto.

Whether these bugs are coming from coreutils or cygwin, or both, I do
not know.
