We already turn on kernel features for several packages, so let's do it
for audit too, since the daemon is useless and fails to load otherwise.
Notice that we also turn NET on, since AUDIT depends on NET, like we do
for the wireguard package.

The Linux tarball checksum was recently updated, including the one for
version 4.9.133. The checksum for this particular version of Linux
misses one character which lead to a build issue as the checksum does
not match:

The commit that added the dependency on host-{bison,flex} did
so because the pre-generated kconfig parser source files were
removed from the kernel tree, in linux-4.16.
But then, in linux-4.17, the pre-generated dtc parser source
files were in turn removed as well.
So, document the two reasons why they are needed, so we don't
accidentally remove them when we (soon) introduce the kconfig
dependencies.
(Also fix the first assignment to LINUX_DEPENDENCIES to be a
simple assignement, not an append-assignment.)

This commit replaces the loop copying out-of-tree DTS into the kernel
tree by a make foreach loop instead of a shell for loop. This allows
to error out if one of the DTS file cannot be copied (for example if

gcc-8 started warning about function aliases that have a non-matching
prototype. This seems rather useful in general, but it causes tons of
warnings in the Linux kernel, where we rely on abusing those aliases
for system call entry points, in order to sanitze the arguments passed
from user space in registers.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82435
Disable the attribute-alias warning introduced by gcc-8 by adding
-Wno-attribute-alias to KCFLAGS.

This issue only applies to kernels built with CONFIG_THUMB2=y, so reword the
comment to make that more clear.
Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
Commit f13477b (linux: config.in: add comment for Arm Cortex-M) added a
comment so that the user that the linux kernel may miscompile with
binutils 2.29+, when the target is an armv7m CPU.
However, the real trigger is a compilation in thumb2 mode, which happens
to be the only option for armv7m CPUs.
We can't know whether the kernel will be built in arm or thumb2 mode,
though, because we do not have that information: it is only available in
the Linux' .config file, which we don;t have access to at the time we
run our menuconfig.
So, relax the conditions under which the comment is made, so that it
appears as soon as binutils are >= 2.29 (i.e. not 2.28, which is the
oldest we support) for ARM CPUs.
