build: enforce linking with --no-undefined, add explicit -lpthread

In investigating x86/sse2 issues in recent webrtc-audio-processing-0.2
release, I found that it was possible for libwebrtc_audio_processing to
contain undefined symbols.

Attached is a patch that addresses this:
* adds -Wl,--no-undefined to libwebrtc_audio_processing_la_LDFLAGS
* adds explicit -lpthread linkage (else, there are undefined references
  to pthread-related symbols)
