Is it actually possible to build a working LGPL2 version of nettle with
mini-gmp? I did look at that option (and the "--with-mini-nettle" option
for gnutls) but couldn't figure it out.

With our current nettle (2.7.1) the problems are
A) it doesn't actually have a "--enable-mini-gmp" option: only one test
binary seems use mini-gmp
B) the gmp files that are included are actually LGPL3 (so even if we could
use them, it would not help the end goal much)
