Thanks for your reply and good to know.

Having looked a bit into olm and emscripten I can imagine a few possible
solutions:

- binaryen is a build dep for emscripten "only" for running the tests
(<!nocheck>). This suggest to me, that it should be possible to get a build
going without the tests. 
I've tried running building with DEB_BUILD_OPTIONS=nocheck and dropping the
build dep on binaryen, but this alone didn't stop the build from failing.
d/rules is rather complex beast and I haven't managed to rip everything
"unneeded" out. Maybe someone more knowledgeable will have more success..
Although I'm not sure how good of an idea it would be to simply skip the tests.

- Drop the javascript bindings for olm (libjs-olm). The only reverse dependency
of libjs-olm is libjs-matrix-sdk which itself has no reverse dependencies.

- Have someone maintain binaryen and emscripten and always upgrade in lockstep,
as the sources [0] suggest, that the actual and "expected" binaryen version at
most differ by one version number.

Maybe there are other ideas of how to resolve this.

If no other solution presents itself I'm inclined to drop libjs-olm in a NMU
with DELAYED/7.
