Arbitrary dependencies on CONFIG_LOCALVERSION of kernel config

The pmbootstrap install step seems to have some arbitrary hard requirement that the CONFIG_LOCALVERSION of a the kernel config matches the kernel package name, requiring that (in our case) we either keep the LOCALVERSION as -postmarketos-qcom-sdm845 in our kernel, even though it's used by other distros, or that we remember to manually edit it every time we regenerate the config.

This isn't inherently an issue, but can be a weird hurdle for new porters, and somewhat frustrating in the long run. Ideally we should have the kernel package fixup the localversion, and then depend on the kernel package name instead of the config file. Or not depend at all and either glob it or otherwise detect it (from kernel output?).

See !2168 (merged)

Can't you just set it in APKBUILD? like https://gitlab.postmarketos.org/postmarketos/pmaports/-/blob/master/device/main/linux-purism-librem5/APKBUILD#L54

Or is .config setting required anyway?

@sdm845-mainline what's the story here?

I m not sure where the issue is. I did this build on a fully zapped environment. I got issue during pmbootstrap install with mkinitfs not wiring up this properly postmarketos-qcom-sdm845 (the flavor specified in APKBUILD) and sdm845 (specified in config file). So i ended up with errors like:

The line mkinitfs -o /boot/initramfs-postmarketos-qcom-sdm845 5.12.0-sdm845 seems weird as its appending -sdm845 after the kernel version rather than -postmarketos-qcom-sdm845.
