Of course, reading this again now teaches me to read more closely next time: the nostrip option clearly gets around the dh_strip problems I reported elsewhere. Nevertheless, I muddled through a build with some hacked up dh_strip statements of the following form in debian/rules.d/binary-*.mk: if ! dpkg-architecture -f -t$(DEB_TARGET_GNU_TYPE) -c dh_strip ... ; \ then dh_strip ... ; fi Here, ... refers to whatever arguments are being passed to dh_strip in each place. Naturally, this is a brute-force approach, but I found that although some places take kindly to the dpkg-architecture hack, others (particularly in the gccgo rules) appear to be used in both native and cross-building contexts. So I've now managed to build i386 packages for the gcc 4.9 toolchains, which were absent from the toolchains.secretsauce.net repository.
