We used to put a "compiler-gcc6.h" file inside every vendor kernel's
aport. This is redundant and only works with GCC6. With this patch,
a common "compiler-gcc.h" file will be used, that works independently
of the GCC version.
The file is from Decatf's android_kernel_samsung_p4 repository, where
it was taken from upstream Linux, but adjusted to work with older
vendor kernels (different #ifndef check at the top etc).

This introduces a new .shared-patches folder. New
"pmbootstrap aportgen" code will make use of this, and create symlinks
to the patches inside that folder when running
"pmbootstrap aportgen linux-..." (or using the new device wizard).
All kernels compile again, after the GCC 8 upgrade.
All 3.x kernels have been changed to use GCC 6 now, because we can't
say for sure that they boot with GCC 8 even if we made them compile
with that newer GCC. If someone wants to test a kernel for a newer
device which they can test, see the instructions on
<https://postmarketos.org/vendorkernel>.
The linux-sony-castor-windy 4.x kernel did not compile out of the box
with the latest GCC, so we set it to GCC 6 as well. This can probably
be fixed easily.
linux-teclast-x80-pro: removed Werror and updated to latest 4.14 kernel
from kernel.org, otherwise this would not compile anymore (tested with
both GCC 6 and 8, probably incompatibility with the latest binutils or
something).
This commit will take too long to compile in CI, so let's [skip ci].
I've compiled all kernels multiple times and fixed them up until all of
them were working again.

If a user has an editorconfig plugin for their editor,
it will enforce tabs instead of spaces for indentation
for APKBUILD files. It ignores other files in the repo.
I thought only having specific symlinks was enough, and it was for one
kernel. However, to make sure it works with all kernels, let's just add
symlinks for all the binutils.
* remove everything that causes conflicts when installing gcc6 and
gcc6-armhf side by side
* fix up the existing "if cross compiling" code path to use the
/usr/gcc6 prefix
* link binutils binaries to the locations they are expected to be
by gcc (this took me hours to figure out....) as well as by the
linux build system with CROSS_COMPILE
* link all gcc binaries to /usr/bin/gcc6-*
Based on the last version from Alpine, but installed to /usr/gcc6 and
with pretty much everything disabled except for the C compiler.
We can probably throw out a lot of patches, and make the APKBUILD much
smaller. But let's focus on making it possible to compile old kernels
again first. There's still a lot to do for that, see #103.
