Unable to build 0.7.4

When trying to build 0.7.4 on Fedora 38, I'm getting this error:

make: *** [Makefile:77: root_fs] Error 1

This happens for make everything VERSION="0.7.4", make aboot, make root_fs, and make recovery_fs (didn't test any others). I've tried both the release tarball and cloning the repo in its current state.

Hi! I patched this in the development branch but didn't in kirkstone. Long story short a variable that didn't need to be specifically set now needs to be set, even if empty.

Please apply this inside SDK_PATH/yocto/meta-qcom/conf/machine/include/mdm9607.inc https://github.com/the-modem-distro/meta-qcom/commit/9fee8a2c0a297869088d6c6a10410ed038032ca3

Looks like that fixes it, thanks.
