I don't think any change in xserver-xorg-video-siliconmotion caused

I agree (and stated so in my original mail), the failure first appeared
in a binnmu so whatever change triggered it was outside the
xserver-xorg-video-siliconmotion package.
Please could you compare output of:
$ gcc -I/usr/include/pixman-1 -E
xorg-server-1.16.4/hw/xfree86/common/compiler.h> a.txt
$ gcc -I/usr/include/pixman-1 -E
xorg-server-1.17.1/hw/xfree86/common/compiler.h> b.txt
on AArch64, with the sources from jessie and sid:
http://httpredir.debian.org/debian/pool/main/x/xorg-server/xorg-server_1.16.4-1.dsc
http://httpredir.debian.org/debian/pool/main/x/xorg-server/xorg-server_1.17.1-2.dsc
Testing in my (far from up to date) sid arm64 qemu chroot I get the
attatched diff.
There were changes in that header for arch-specific handling of outb()
and friends. This could be a regression; or possibly wrong definitions
were used before (allowing it to build when it should not have).
It looks like stub definitions (writes ignored, reads return 0) were
removed.
