Hi Daniel,

I reported this on IRC already, but I need some way to track (a git
commit would have done as well) this issue, so I am sending you a bug
report now:

When considering whether to pass --disable-asm or whether to build a
udeb, the packaging examines the architecture we are building on, not
the architecture we are building for. Thus we would e.g. pass
--disable-asm when building for amd64 on ppc64. This is not what you
intended and causes cross builds for armel to simply fail.

Patch:

    sed -i -e '/^ifeq (\$(DEB_BUILD_ARCH),[a-z]/s/BUILD/HOST/' debian/rules
