[SOLVED] Can't compile any kernels or modules

Question

I can't compile the kernel, or any kernel modules. I tried the [core] kernel from ABS and the linux-ck kernel from AUR. I also tried to build vhba and nvidia modules.
I tried the standard cflags and many others.
All kernel compiles fail (immediately) with:
scripts/mod/empty.c:1:0: error: code model kernel does not support PIC mode
/* empty file to figure out endianness / word size */
^
edward_81 had the same problem, with a default makepkg.conf and linux-mainline, which was never resolved.
I don't know why this file is being compiled in PIC mode. I have not explicitly enabled PIC anywhere I know of. I checked everywhere I know to look.

Will try.
Finally got this working:
Please add V=1 to the make command on line 89 and rebuild with MAKEFLAGS="-j1" to get verbose output.
make -f ./scripts/Makefile.build obj=scripts/genksyms
