Package: src:gcc-7 Followup-For: Bug #861734 Please build the native gnat on armel by reverting svn://anonscm.debian.org/gcccvs/branches/sid/gcc-7@9434 6ca36cf4-e1d1-0310-8c6f-e303bb2178ca Since then, the link step for the tools has changed a lot, and a recent build log would be more helpful. Moreover, --as-needed -z,defs have been added to libgnat linker options, and should help locating the problem.
