  35 # --cross-compile-prefix Add specified prefix to binutils components.

  38 #               interfaces deprecated as of the specified OpenSSL version.

  52 # no-dso        do not compile in any native shared-library methods. This
  53 #               will ensure that all methods just return NULL.

  55 # [no-]zlib     [don't] compile support for zlib compression.
  56 # zlib-dynamic  Like "zlib", but the zlib library is expected to be a shared
  57 #               library and will be loaded in run-time by the OpenSSL library.

1906 Please consider configuring with the flag --unified .
1907 It's to test out a new "unified" building system.
1908
1909 One cool feature is that you can have your build directory elsewhere,
1910 for example:
1911
1912     make clean          # Clean the current configuration away
1913     mkdir $plausible_builddir
1914     cd $plausible_builddir

1916     make
