Don't leak symbols into static library

[Simon Josefsson]

Before patch below:

jas at mocca:~/src/libgcrypt$ nm -B src/.libs/libgcrypt.a |grep ' T '|grep -v gcry|grep -v __
000059c0 T Camellia_DecryptBlock
00005b90 T Camellia_Ekeygen
00005850 T Camellia_EncryptBlock
00003020 T camellia_decrypt128
000049b0 T camellia_decrypt256
00002530 T camellia_encrypt128
00003b10 T camellia_encrypt256
00000000 T camellia_setup128
00005b30 T camellia_setup192
00000f10 T camellia_setup256
00001d30 T ac_data_extract
