So, this seems to be a problem with dh_strip. Looking at the dh_strip code indicates that a function called cross_command is provided in the following file: /usr/share/perl5/Debian/Debhelper/Dh_Lib.pm This appears to compare DEB_BUILD_GNU_TYPE and DEB_HOST_GNU_TYPE, and only if they are different does it generate a command prefixed with the latter. So, to coerce it to use the appropriate objcopy command on foreign libraries, the following appears to be necessary (for my system): DEB_BUILD_GNU_TYPE=i586-linux-gnu \ DEB_HOST_GNU_TYPE=mipsel-linux-gnu \ dh_strip ... The most pertinent reference to this that I could find was the following comment on a bug in Launchpad: https://code.launchpad.net/~hrw/ubuntu/precise/gcc-4.6/cross- fixes/+merge/82269/comments/177796 Since dh_strip seems to be used a lot in the debian/rules.d files for the gcc packages, I do wonder what the fix for this is meant to be.
