nettle: bump to 3.3, enable x86_gcc2, add tiny gcc2 patch.

* Unlike 3.2, which would not build on x86_gcc2 without a patch,
  3.3 builds fine without any patch. A tiny one is only required
  for "make check".
* Update (GNU) LICENSE: LGPL v2.1 -> GPL v2 + GPL v3 + LGPL v3.
* Switch SOURCE_URI to https.
* Add $secondaryArchSuffix to cmd:libtoolize in BUILD_PREREQUIRES.
* Drop PATCH(), previously used to skip -lm and add -lroot.
* Drop unneeded calls to libtoolize and autoconf.
* Add TEST() with "make check" (and an appropriate LIBRARY_PATH.)
  All tests are OK, except for the Camellia cipher on x86_gcc2.
