This is where it seems to get stuck, it's been stuck on CPU 100% for
one hour now:

    [CC] vp9/vp9_cx_iface.c.o
libtool: compile:  gcc -fPIC -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=0
-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -Wall
-Wdeclaration-after-statement -Wdisabled-optimization -Wpointer-arith
-Wtype-limits -Wcast-qual -Wvla -Wimplicit-function-declaration
-Wuninitialized -Wunused-variable -Wno-unused-function -I.
-I/opt/pkg.obj/multimedia/libvpx/work.ultra10/libvpx-1.3.0 -c
vp9/vp9_cx_iface.c  -fPIC -DPIC -o vp9/.libs/vp9_cx_iface.c.o

I'm beginning to think maybe it's a compiler bug??
