Also there's a strange hickup with Gem, which fails to configure on first pass (problem with PROG_OBJCXX not defined or so), but restarting the compilation as-is works.
Ooops. It seems I mixed things. I had to uncomment the AC_PROG-OBJCXX in configure.ac and apply the cross-compilation workaround patch from the debian packaging stuff.
Note: up to data git Gem does not exhibit this behavior and builds fine out of the box.
