PKGBUILD: untuck the way generic subarch is set

Previously a really convoluted two stage 'yes' invocation
was used with that required weird formatting.

Switch to using the good old configs enabling.

 - `_use_current`: Will use the configuration of the running kernel, if the running kernel is compiled with `IKCONFIG_PROC`

+## Branches
+This repository (at least if you view it on [sos!git](https://git.staropensource.de/JeremyStarTM/aur-linux-clear))
+has two branches: `master` and `develop`. The `master` branch is the stable branch, where stable changes
+are introduced. The `develop` branch is (as you might have already guessed) the development branch.
+
+Please only submit PRs to the `develop` branch. Pull requests to the `master` branch will be rejected.

 ## License
-This package does not yet have a license as the original repository (before [me](https://git.staropensource.de/JeremyStarTM) becoming it's maintainer) did not have one yet.
-I have contacted [metak](https://aur.archlinux.org/account/metak) (the previous maintainer) to negotiate a license.
+The linux-clear package is licensed under the BSD Zero-Clause License.
+I ([JeremyStarTM](https://git.staropensource.de/JeremyStarTM)) negotiated it with [metak](https://aur.archlinux.org/account/metak) (the previous maintainer) and [yarost12](https://git.staropensource.de/yarost12) (co-maintainer).
 
 ## Build tool
-*If you want a dead simple way to compile this package, you can [try out my build tool](https://git.staropensource.de/JeremyStarTM/jstm-optimized). It includes a few no nonsense changes to the kernel configuration and allows you to configure the PKGBUILD in a simple manner to decrease build time. If you don't want that, using `makepkg` as-is works fine too.*
