Fixed linker arguments for libhogweed.so

ChangeLog

+2014-05-28  Niels Möller  <nisse@lysator.liu.se>
+
+	* configure.ac (LIBHOGWEED_LIBS): Be explicit and link
+	libhogweed.so with libnettle.so, not -lnettle.
+	(LIBHOGWEED_LINK): Drop -L. flag, no longer needed, and previously
+	not at the correct position in the link command line.
+

 	* examples/ecc-benchmark.c: If mpn_sec_powm is available,

configure.ac
