configure: improve nettle, gmp, and hogweed soname detection
Some linkers might optimize away the libraries passed on the
command line if they aren't actually needed, such as gnu ld with
--as-needed.
The ldd output then won't list the shared libraries and the
detection will fail.
Make sure nettle and others are really used.
