[Cin] Compiling Cinelerra-GG for (l)ubuntu 16.04.6 ppc32

[Andrew Randrianasulu]

Hello again, everyone!

After spectacular failure about building working Cinelerra-GG on ppc64le I moved 
to more common ppc platform - emulated powerMac!

Well, I only installed ubuntu with qemu's -M mac99, and then moved resulted 
image as virtual drive to another type of machine, supporting SMP (and thus 
faster for compiles).

install:

qemu-system-ppc -display sdl,gl=on -M mac99 -cpu 
g4 -cdrom /mnt/lubuntu-16.04-desktop-powerpc.iso   -drive 
format=raw,file=/mnt/Ubuntu-16.04-ppc.img,index=0,if=virtio   -device 
qemu-xhci -device intel-hda -device virtio-keyboard-pci -nic 
user,model=virtio -usb -device virtio-mouse-pci -m 2000 -g 1024x768x32 -boot d

run (assumes 64-bit qemu host, so smp will be faster actually, using qemu 3.1.0 
in my case):
ppc64-softmmu/qemu-system-ppc64 -display sdl,gl=off -smp 4 -M ppce500 -cpu 
e5500  -drive 
format=raw,file=/mnt/Ubuntu-16.04-ppc.img,index=0,if=virtio -kernel /mnt/linux-image-4.20.12-X1000_X5000/X5000_and_QEMU_e5500/uImage-4.20 -append "rw 
root=/dev/vda3"  -device virtio-vga,virgl=off  -device qemu-xhci -device 
intel-hda -device virtio-keyboard-pci -nic user,model=virtio -usb -device 
virtio-mouse-pci -m 2000 -g 1024x768x32

gl=off makes colors normal, but console slower ....
intel-hda, qemu-ehci and ES1370 fail with dma alloc errors.


lightdm will fail to start, log in and 'systemctl disable lightdm'
kernel from http://www.xenosoft.de/linux-image-4.20.12-X1000_X5000.tar.gz

I already run into small failure in libvpx-1.7.0, it will probably exist in 
libvpx-1.8.0 as well. New libvpx assumes you build for ppc64. Patching 
configure seems to help:

I think you can just add ppc-linux-gcc line without removing ppc64 line.
