Subject: [PATCH] OpenBSD: register machine cpu "macppc" as cpu_family "ppc"

On OpenBSD, the main PowerPC machine is known as macppc, while the processor
family is powerpc:
$ uname -{m,p}
macppc powerpc
$ echo 'import platform; print (platform.machine())' | python3
macppc
$ echo 'import platform; print (platform.processor())' | python3
powerpc

This allows for e.g. GLib configure to properly detect that cpu:
Build machine cpu family: ppc
Build machine cpu: macppc
While it failed before with: WARNING: Unknown CPU family 'macppc' <snip>
