This is in the category "intended breakage".
We had a similar issue in the top-level Makefile which Paul (IIRC)
helped me to fix long time ago.

To fix popwerpc I suggest something along these lines.
[Note: I did not test it - please do so.

[PATCH] powerpc: fix build with make 3.82

Thomas Backlund reported that the powerpc build broke with make 3.82.
It failed with the following message:

    arch/powerpc/Makefile:183: *** mixed implicit and normal rules.  Stop.

The fix is to avoid mixing non-wildcard and wildcard targets.

Thanks, this seems to fix the first issue, but then I get the same erro on the following line 190:

190: bootwrapper_install %.dtb:
191:        $(Q)$(MAKE) ARCH=ppc64 $(build)=$(boot) $(patsubst %,$(boot)/%,$@)
