I plan to do so on the weekend. Snowboarding conditions look bad, I
should have time to spare. ;-)

Afaiu the shlibs info for the udeb is provided in the regular library
package:

ametzler at argenau:/tmp$ mkdir foo && cd foo && \
  ar -x /chroots/sid/var/cache/apt/archives/libgpg-error0_1.10-0.2_i386.deb &&\
  tar xzf control.tar.gz
ametzler at argenau:/tmp/foo$ cat shlibs
libgpg-error 0 libgpg-error0 (>= 1.10)
udeb: libgpg-error 0 libgpg-error0-udeb (>= 1.10)

When building libgcrypt11-udeb (dh|_dpkg-)shlibdeps searches for
matching udeb lines in the shlibs file and uses them for resolving the
udeb's dependencies. Configured repositories do not play a role in
this. Therefore the build-depends works.

I have not really got a documentation to back this, but a little bit
of data. I played around a little when libgpg-error0 1.10-0.2 was
available in incoming (but not yet apt-able). Building
libcrypt11 against the locally installed libgpg-error0
1.10-0.2 produced correct udeb depends where 1.10-0.1 failed.
