Some barebox targets need to build host tools (for example rockchip64
uses scripts/rkimage) that require some host libraries, such as
host-openssl or host-libusb. These are detected by the Barebox build
system using pkg-config.
In order to allow supporting such Barebox configurations, we add two
new options: BR2_TARGET_BAREBOX_NEEDS_OPENSSL and
BR2_TARGET_BAREBOX_NEEDS_LIBUSB that respectively allow to ensure that
host-openssl and/or host-libusb are built before Barebox.
Additionally, $(1)_MAKE_ENV is adjusted to ensure that when pkg-config
is run by the Barebox build system, it finds host libraries. This is
similar to what is done in U-Boot.
This allows to fix the following build failure:
HOSTCC scripts/rkimage
Package openssl was not found in the pkg-config search path.
Perhaps you should add the directory containing `openssl.pc'
to the PKG_CONFIG_PATH environment variable

The variable 'KERNEL_ARCH' is actually a normalized version of
'ARCH'/'BR2_ARCH'. For example, 'arcle' and 'arceb' both become 'arc', just
as all powerpc variants become 'powerpc'.
It is presumably called 'KERNEL_ARCH' because the Linux kernel is typically
the first place where support for a new architecture is added, and thus is
the entity that defines the normalized name.
However, the term 'KERNEL_ARCH' can also be interpreted as 'the architecture
used by the kernel', which need not be exactly the same as 'the normalized
name for a certain arch'. In particular, for cases where a 64-bit
architecture is running a 64-bit kernel but 32-bit userspace. Examples
include:
* aarch64 architecture, with aarch64 kernel and 32-bit (ARM) userspace
* x86_64 architecture, with x86_64 kernel and 32-bit (i386) userspace
In such cases, the 'architecture used by the kernel' needs to refer to the
64-bit name (aarch64, x86_64), whereas all userspace applications need to
refer the, potentially normalized, 32-bit name.
This means that there need to be two different variables:
KERNEL_ARCH: the architecture used by the kernel
NORMALIZED_ARCH: the normalized name for the current userspace architecture
At this moment, both will actually have the same content. But a subsequent
patch will add basic support for situations described above, in which
KERNEL_ARCH may become overwritten to the 64-bit architecture, while
NORMALIZED_ARCH needs to remain the same (32-bit) case.
This commit replaces use of KERNEL_ARCH where actually the userspace arch is
needed. Places that use KERNEL_ARCH in combination with building of kernel
modules are not touched.
There may be cases where a package builds both a kernel module as userspace,
in which case it may need to know about both KERNEL_ARCH and
NORMALIZED_ARCH, for the case where they differ. But this is to be fixed on
a per-need basis.

Commit 5b95a5dc2 (support/download: change format of archives generated

are named, adding a "format-version" identifier right between the
package version and the file extension.
Commit c043ecb20 (support/download: change format of archives generated
from svn) did so for archives generated from a subversion checkout.
However, for a few packages, we manually force the _SOURCE variable,
because we want to share the archive with another package, to avoid
downloading and storing those archives twice. This is the case for:
- linux-headers and linux
- barebox-aux and barebox
When the generated tarballs were renamed with the aforementioned
commits, those packages were not updated accordingly.
Fix that by manually propagating the per-site-method format-version.

The buildroot custom bareboxenv compile command misses the additional
include path 'scripts/include' to gain access to the local copy of the
kernel header files (which leads to compile error when using an older
toolchain).
This could be fixed by enhancing the custom bareboxenv compile command
(see [1]) or by using the barebox build system by simply enabling the
CONFIG_BAREBOXENV_TARGET option (available since April 2012, see [2])
instead (as suggested by Yann E. MORIN).

When barebox, and thus barebox-aux, are downloaded from a git tree, then
barebox-aux download fails because a hash check is attempted on the
downloaded archive:
Could not fetch special ref 'v2020.03.0'; assuming it is not special.
ERROR: No hash found for barebox-aux-v2020.03.0.tar.gz
This is because we only exclude from the check the archive of the bare
barebox:
BR_NO_CHECK_HASH_FOR += $(BAREBOX_SOURCE)
However, the default name of an archive is based on the package name,
which for barebox-aux is not 'barebox'.
Since barebox-aux really uses the exact same source as the bare barebox,
it should also share the archive name.
This has two direct consequences and advantages:
- the hash check is completely avoided for the barebox-aux archive;
- the barebox-aux archive is not downloaded as it is already
downloaded for barebox.

Instead of excluding the hash specifically for the custom tarball and
custom version cases, exclude it always except in the one case where
we do have a hash: the latest version.
This simplifies the code a little because soon we will add hash checks
for git as well, so we also need an exclusion in that case.
It is not needed to exclude it twice for barebox and barebox-aux,
because they use the same source tarball and barebox-aux can only be
enabled if barebox is enabled. So simplify even further by pulling
the exclusion logic out of inner-barebox-package.
