Trying to link both aecm/aecm_core_mips.cc and aecm/aecm_core_c.cc into
the same library results in an error because they both try to implement
webrtc::WebRtcAecm_ProcessBlock():

The MIPS-specific file is a replacement for the other, unlike the NEON
case. Don't add the default implementation unconditionally, add it only
for non-MIPS builds.
