guile-cairo fails to cross build from source for two distinct reasons.
The first reason is that configure fails running guile-3.0 and gives up.
guile-3.0 is M-A:allowed and it occurs twice in the dependency chain.
One of them is annotated :any and the one via guile-library is not. As a
result, apt picks the host one and that happens to not be runnable. It
is guile-library that forces the host one. I believe that its dependency
is correct, because guile-library provides shared objects to be loaded
into guile-3.0. The question really becomes whether guile-cairo needs to
load those libraries. After some digging, I figured that yes it does,
but only for running tests. So annotating the dependency <!nocheck>
makes the dependency go away for cross builds (as apt can then use the
build's guile-3.0) and a nocheck build still exactly reproduces a
regular build.
What fails next is guile-snarf. I've see than for guile-gnutls already
and the cause is that guile-snarf defaults to using the build
architecture cpp. Basically whenever using guile-snarf in a build, we
must export CPP.
I'm attaching a patch addressing both for your convenience. The
cross.patch part should be upstreamable.
