Subject: [PATCH] libvpx: Explicitly link with pthread support

When building for the native build host, explicitly add the -pthread
option to link against the pthread libraries. This errors like:

  vp9_encoder.c:(.text+0x2073): undefined reference to `pthread_once'

when building the native variant
