> ld: fatal: symbol referencing errors. No output written to avprobe

This failure is caused by badly working DCE.

Every call of the ff_rtmpe_encrypt_sig function from libavformat/rtmpproto.c
is protected by following conditional expression:
if (CONFIG_FFRTMPCRYPT_PROTOCOL && rt->encrypted)

CONFIG_FFRTMPCRYPT_PROTOCOL is zero but it does not stop suncc:
% nm libavformat/rtmpproto.o | grep ff_rtmpe_encrypt_sig
                 U ff_rtmpe_encrypt_sig
