[i9070][i9100] Build kernels natively
Created by: ollieparanoid
This PR removes the need of the _pmb_build_in_native_chroot
variable inside the APKBUILDs. Instead of compiling inside a native armhf
chroot, to get Alpine's busybox-static
binary, the armhf
version gets installed inside the x86_64
chroot. Just like musl-armhf
.
This speeds up compiling a lot and removes the need for the _pmb_build_in_native_chroot
hack, while still using Alpine's busybox instead of the pre-compiled blob shipped with the kernel sources.
