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.

 ## 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.*
