Actually, I'm building with ppc64le as emulated by qemu right now.

https://buggy.link/2018/01/31/ppc64le-on-x86_64-qemu-full-system-emulation.html

https://wiki.alpinelinux.org/wiki/Ppc64le

qemu-system-ppc64 -m 1024 -hda alpine_disk.img -cdrom 
alpine-vanilla-3.7.0-ppc64le.iso -display sdl,gl=on

(yes, it works with graphics, even if I was forced to use 'xf86-video-fbdev' via 
custom xorg.conf due to nomodeset kernel option)

It seems few third-party libs in Cinlerra-GG fail to guess os correctly, but 
replasing their config.guess with one provided by package (automake-1.15) fixed 
this error ...

https://bugzilla.redhat.com/show_bug.cgi?id=1139354

ooops, guess liba52 from thirdparty just wrongly guessed oss as soundsystem :}
time to fix this too
