Actually, I went back to v4.17, and I have the same errors.

I used:

$ make ARCH=parisc O=build_parisc generic-64bit_defconfig
$ PATH=/home/alex/wip/toolchain/gcc-8.1.0-nolibc/hppa64-linux/bin:$PATH 
make ARCH=parisc CROSS_COMPILE=hppa64-linux-

I downloaded the crosscompiler here: 
https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/8.1.0/
