    openssl: Allow it to be build with make -jN N > 1 · 5cb43f32

    There is a story for OpenSSL build to be broken for `make -j`. Gentoo-
    and various other people proposed fixes, at least from 2008, but for
    some reasons (patch does not work with BSD make, upstream forgot to
    apply, etc) they are not applied to main codebase.
    
    What we can do is to "cherry-pick" the patch from Gentoo to speed-up
    OpenSSL build. On a typical 8-cores i7 node, with the following test
    buildout:
    
        [buildout]
        extends =
          slapos/stack/slapos.cfg
          slapos/component/openssl/buildout.cfg
    
    after full build
    
                        time (rm -rf parts/openssl && ./bin/buildout install openssl)
    
        MAKEFLAGS=-j1   1m48s
        MAKEFLAGS=-j8   0m53s
    
    and the timing does not subtract time to e.g. download the package from
    network, so the building speedup itself is even more.
