Nevermind, I got the build stuck at vp9_cx_iface on parkes, and on the
cross compiler at a faster build machine. It gets stuck in the first
common subexpression elimination optimization pass (cse1) in a partial
clone of function validate_config. It fails even with -O2.
I found out that compiling with -fno-cse-follow-jumps in addition to -O3
or -O2 makes it finish compilation very quickly, presumably at some loss
of optimization. You might want to use that for now, at least until I
debug the compiler it properly. That might take a while, though.
