Error building ISO when using generic kernel build

[abelian424]

I've noticed that the build works fine if I populate ./packages with linux-mainline-bcachefs or linux-bcachefs-ck that has a built package. But if I let the script build the package with generic settings, the ISO build fails. I'm not really sure what the problem is, but I recommend pre-building the linux bcachefs kernel with the right processor customizations for your CPU for now. Since when it comes time to install arch it just reuses the bcachefs kernel package from the iso anyway, you'll save time and later effort by doing this. To do so, just git clone the aur repo, do a makepkg -src (or -sric if you want to install as well) in the package directory, and then copy the entire directory into your packages folder for archiso-bcachefs-mainline(-ck). If the script detects the package, it won't try to rebuild it.
