This still has the cross-build problems, no?

Yes, but that issue is more general to CONFIG_BUILD_DOCSRC.
This is just a build failure on x86-32.

Applying this patch on top of v3.18-rc1 to get it to build for 32 bit
x86 triggers this build error (when calling "make -s mrproper", which is
done early in the build of a Fedora kernel rpm):
Documentation/vDSO/Makefile:13: *** missing separator. Stop.
make[1]: *** [Documentation/vDSO] Error 2
make: *** [_clean_Documentation] Error 2

Using
ifeq ($(CONFIG_X86_32),y)

fixes that error. And with that space added this patch unbreaks the
build of v3.18-rc1 for 32 bit x86.

Thanks,
