I've seen two issues with 1.2 beta on Fedora 27 (gcc-7 plus a bunch of
tightened cflags) across a few architectures.

First is on all arches:

undefined reference to `silk_LPC_inverse_pred_gain_c'

Second is a few of them have this error:

undefined reference to `opus_select_arch'

all the build logs for the various arches can be found here:

Let me know if you've got any queries.
