The getconf interface is problematic as it does not correctly support cross-building. I clarified this in the lintian tag for the LFS support with: https://salsa.debian.org/lintian/lintian/-/commit/ba9c7fd96801e3c796d0233b4f7432e55dffe057 but now that the lintian LFS tag has been removed, that got lost. In any case, dpkg-buildflags already supports setting LFS flags with: export DEB_BUILD_MAINT_OPTIONS = abi=+lfs which should support cross-building correctly. I was going to close this report as invalid, but I guess I can instead document that the getconf interface should not be used in the dpkg-buildflags man page (although I'm not sure it would have helped here, as I assume the man page was not checked?). Thanks, Guillem
