    gotools: Workaround non-reproduceability of automake
    
    The regen bot recently flagged a difference in gotools/Makefile.in.
    Trying it locally, it seems pretty random
    for i in `seq 20`; do PATH=~/automake-1.15.1/bin:~/autoconf-2.69/bin:$PATH automake; echo -n `git diff Makefile.in | wc -l`" "; done; echo; for i in `seq 20`; do
    +PATH=~/automake-1.15.1/bin:~/autoconf-2.69/bin:$PATH setarch x86_64 -R automake; echo -n `git diff Makefile.in | wc -l`" "; done; echo;

    I'm not familiar with automake/m4 enough to debug that, so I'm

            * Makefile.am (install-exec-local, uninstall-local): Add goals
            on the else branch of if NATIVE to ensure reproducibility.
            * Makefile.in: Regenerate.
