Build failure for minimal builds

Werner,

Building a minimal libgcrypt 1.4.1 using:

./configure --enable-digests="md5 sha1 sha256" --enable-ciphers="arcfour des aes" --enable-pubkey-ciphers="rsa dsa"

results in a library that calls an unknown symbol:

../src/.libs/libgcrypt.so: undefined reference to `_gcry_ecc_get_param'

This patch makes sure the function isn't called if ECC is disabled:

However, the self-tests fail catastrophically. The remaining patch
fixes that too.
