Regression: pmbootstrap can't build linux-postmarketos-rockchip: can't find /home/pmos/build/src//include/config/kernel.release

Using the envkernel.sh flow, with something like the following steps:

source /path/to/pmbootstrap/helpers/envkernel.sh
cp /path/to/postmarketos/var/pmbootstrap/cache_git/pmaports/device/community/linux-postmarketos-rockchip/config-postmarketos-rockchip.aarch64 arch/arm64/configs/rockchip_defconfig
make rockchip_defconfig
make -j
pmbootstrap -v --details-to-stdout build --envkernel linux-postmarketos-rockchip

The last step fails with the following (trimmed):

[...]

If I revert this commit in bootstrap, this process no longer fails:
