Our build/make changes break incremenetal builds with prebuilt dtb dir
(see discussion here: https://android-review.googlesource.com/c/platform/build/+/1134337/1/core/Makefile )
Instead of using the AOSP recipe, just define our own and use it by not defining
BOARD_PREBUILT_DTBIMAGE_DIR

* OpenSSL cannot be statically linked because of
getaddrinfo and gethostbyname calls.

Previously, this would be a full compile prefix
(e.g. prebuilts/gcc/.../bin/aarch64-linux-gnu-). Since we're adding
this to PATH, it only needs to be prebuilts/gcc/.../bin.
Also remove the extra /bin/ added by kernel.mk.

The kernel make command is executed in the build root. Without absolute
out paths, kernel out start with "out/" meaning it would be created in
the kernel source. Add BUILD_ROOT to the argument to ensure it's always
made in the actual out/ dir.

The GCC toolchains are no longer added to the path by default, so
we need to hardcode the full paths for these. Also set variables
for every arch, and then set the toolchain to the arch specific var.
This is so we can set the ARM32 cross compile flag for vDSO32
enabled kernels.

* -androidkernel ones became symlinks to -android ones long time ago, use
-android executables directly to simplify the logic on these platforms.
* Keep arm on -androidkernel because it doesn't boot for some reason.

Using preinstalled system headers and libraries is no longer allowed.
So we're gonna make our own prebuilts/openssl so we can build kernels.

The built ccache command is now deprecated and spits out errors. ccache is
also no longer used for the full build unless CCACHE_EXEC is defined. Move
the kernel to the same logic in order to actually use ccache and silence
the warnings.

* Instead of nesting ifeq/else/ifeq/else/endif/endif construction, make
allows the more readable ifeq/else ifeq/else/endif construction. Use it
instead.

These configuration options are set based on the Google configurations
located in kernels
(ex. https://github.com/LineageOS/android_kernel_google_wahoo/blob/lineage-16.0/build.config)
This is composed of 2 parts:
Revert "kernel: Correct CROSS_COMPILE_ARM32 toolchain"
This reverts commit c77bb3a5ba.
This breaks builds when building with upstream commit
ad15006cc78459d059af56729c4d9bed7c7fd860. That commit fixes LD being
used from outside the path, however androidkernel toolchains don't
have elfedit. Google specifically doesn't use androidkernel, so we
need to follow them on this.
Set CROSS_COMPILE_PREFIX to aarch64-linux-android- for clang builds
Upstream commit ad15006cc78459d059af56729c4d9bed7c7fd860 makes the
kernel build system use GCC toolchains for elfedit, so we have to
actually use a real GCC toolchain, not the androidkernel one.

Currently we handle the DTBO images from start to finish, including
AVB footers, and just drop them in $(PRODUCT_OUT)/dtbo.img when done.
While this works for the most part, we are limited in what we can do
with the DTBO images. For example non-A/B device recovery images must
have a copy of the DTBO image appended to recovery (see AOSP docs:
https://source.android.com/devices/bootloader/recovery-image ). This
means that we need to pass the pre-AVB dtbo image into
BOARD_PREBUILT_DTBOIMAGE in order to let the AOSP build system handle it.
This commit reworks the way the DTBO images are built, placing them at
$(PRODUCT_OUT)/dtbo-pre.img instead and setting BOARD_PREBUILT_DTBOIMAGE
to that path so the AOSP build system can pick the images up and sign
them and append to recovery (for applicable devices).

Kernel source settings should always come at BoardConfig population
time so things that use the variable later don't end up pointing to
an empty or wrong variable.

tasks: kernel: Honor prebuilt kernel flag
For devices that want to use a prebuilt kernel, TARGET_KERNEL_SOURCE
would still be set to TARGET_AUTO_KDIR, meaning the build system would
still try to build the kernel if TARGET_AUTO_KDIR was present.
Setting TARGET_PREBUILT_KERNEL indicates this is not wanted, so don't
attempt to do it.
