To recap - the solution was to add CROSS32_COMPILE=hppa-linux- , e.g.:

make ARCH=parisc CROSS_COMPILE=hppa64-linux- CROSS32_COMPILE=hppa-linux-

The better solution (for kernel >= v5.17) is to simply leave out the CROSS_COMPILE/CROSS32_COMPILE
parameters and let the Makefile autodetect everything:

make ARCH=parisc -> 32bit kernel
make ARCH=parisc64 -> 64bit kernel

It's now documented in the Wiki:
https://parisc.wiki.kernel.org/index.php/Cross_compiler_toolchain#How_to_build_the_kernel
