I'm an idiot. Turns out it's something completely unrelated. Here's
the relevant part of the build failure:

[snip]

In file included from arch/powerpc/boot/../../../lib/decompress_unxz.c:233,
                 from arch/powerpc/boot/decompress.c:42:
arch/powerpc/boot/../../../lib/xz/xz_crc32.c:18:10: fatal error:
linux/crc32poly.h: No such file or directory
 #include <linux/crc32poly.h>
          ^~~~~~~~~~~~~~~~~~~
compilation terminated.
make[4]: *** [arch/powerpc/boot/Makefile:217:
arch/powerpc/boot/decompress.o] Error 1
make[3]: *** [arch/powerpc/Makefile:288: zImage] Error 2

[snip]

It's the xz kernel compression option which is failing, gzip builds
fine (but it's still pointless, powerpc kernels seem to be always
installed uncompressed). Broken .config attached, if relevant.

Sorry for the misdirection.
