build: Fix builds without --with-libgcrypt-prefix nor --with-libgcrypt-libdir. Reported by Manolis Ragkousis <manolis837@gmail.com>. Fixes a regression introduced in 14af289. Before this commit, ./configure would leave LIBGCRYPT_PREFIX and LIBGCRYPT_LIBDIR undefined, leading to LIBGCRYPT_LIBS="-L -lgcrypt" and thus to a link failure. * configure.ac: Make sure $LIBGCRYPT_PREFIX and $LIBGCRYPT_LIBDIR are never empty.
