Mac Mini G4 defconfig ?

Hi there,

Does anyone has working defconfig for a Mac Mini G4 ?

Here is what I tried:

$ cat ./arch/powerpc/configs/g4_defconfig
CONFIG_PPC_FPU=y
CONFIG_ALTIVEC=y
$ make ARCH=powerpc g4_defconfig
$ make -j8 ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- V=1

That is odd. Doing a quick git bisect:

$ git checkout 3298b690b21cdbe6b2ae8076d9147027f396f2b1
$ make -n ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- -f ./Makefile
silentoldconfig V=1
+ make -n ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- -f ./Makefile
silentoldconfig V=1
/bin/sh: line 0: [: -ge: unary operator expected
make -f ./scripts/Makefile.build obj=scripts/basic

I cannot make sense of this shell error, maybe this is unrelated but
things start breaking around this commit.

Even if I discard this shell error, the next error comes with:

Comments ?
Solution is:

$ rm .cache.mk

I guess the cache was not cleared in between my different kernel compilations.

Sorry for the noise

Looks like others are hitting this too and it seems like we'll need to
come up with a solution that avoids this (or at least makes it somehow
clear that a make clean will fix it).  See the thread at
<https://lkml.org/lkml/2017/12/16/315>.
