The Linux buildsystem tries to run the compiler even just for
'kernelrelease' (which we store in LINUX_VERSION_PROBED) and we
sometimes need to use it before the toolchain is available; thus
we get spurious errors on stderr.
Consign stderr to oblivion when computing the 'kernelrelease'.

This commit add an infrastructure to build linux kernel
tools available in the kernel sources.
Currently, the only linux kernel tool packaged in Buildroot
is perf and it's packaged as a separate generic package.
This is a problem for licence information raised in this
thread [1].
Since these tools require to build a Linux kernel, we can
use some hooks in linux package like we did for linux
extensions [2] and remove the perf package.

The ktap package requires some parts of the kernel tracing
infrastructure to be enabled, especially
CONFIG_EVENT_TRACING. However, this option is a blind option in the
kernel, so enabling it in linux.mk has no effect: we need to enable a
non-blind option that selects CONFIG_EVENT_TRACING. We've chosen to
select CONFIG_ENABLE_DEFAULT_TRACERS.
This fixes the build of ktap.

Several packages have some logic to apply custom patches that existed
before the BR2_GLOBAL_PATCH_DIR mechanism: at91bootstrap,
at91bootstrap3, barebox, uboot and linux. Currently, the logic of
those packages to apply custom patches is to match
<package-name>-*.patch, which is not consistent with what we've done
for patches stored in the package directory, and for patches stored in
BR2_GLOBAL_PATCH_DIR: in such cases, we simply apply *.patch.
Therefore, for consistency reasons, this commit changes these packages
to also apply *.patch.

The linux package has a special handling of patches, with quite a bit
of legacy in it. A problem caused by this special handling is that the
linux package calls directly the DOWNLOAD_WGET macro, which means that
the package infrastructure isn't aware of which patches get
downloaded, and it prevents doing changes inside the package download
infrastructure.
This commit changes the handling of patches in the linux package in
the following way:
* The LINUX_PATCHES variable is kept as is: it lists all the patches
mentioned in the Config.in option BR2_LINUX_KERNEL_PATCH. This
option can contain http://, ftp://, https:// URLs, path to local
files or local directories.
This variable is *not* used by the generic package infrastructure,
so it is purely internal to the Linux package.
* The LINUX_PATCH variable is now filled in with the list of patches
that should be downloaded. It is derived from LINUX_PATCHES by
filtering the patches that have http://, ftp:// or https:// in
their path. Since <pkg>_PATCH is handled by the package
infrastructure, it means that those patches are now automatically
downloaded and applied by the package infrastructure.
* The LINUX_APPLY_PATCHES hook is renamed to
LINUX_APPLY_LOCAL_PATCHES, because it is now only responsible of
applying local patches: remote patches are handled by
LINUX_PATCH. The implementation of the hook is changed to filter
out the patches that have already taken care of by LINUX_PATCH, so
that we only iterate through the list of local patches or local
patch directories.

This causes that user can't provide one *.dts file and some other

variable with *.dts files only. All user provided files are copied
into kernel source tree, but only file names suffixed with *.dts
are used for building appropriate *.dtb files.

When Buildroot is configured to append the root filesystem to the Linux
kernel as initramfs, Buildroot sets the path to the initramfs source
dynamically in the Linux configuration file.
As this path is specified as an absolute path, typically being different
for different users of the same project (e.g. containing a username),
saving the configuration to a version control system (for example using
'make linux-update-defconfig') would result in a difference for this
path at every invocation by a different user.
Although this is technically not an issue, it is confusing that this
generates a difference.
Address this issue by using a not-yet-expanded make variable to specify
the path to the initramfs source. That variable will be expanded by the
Linux build system, which uses it both as a Makefile variable and a
shell variable; thus, it needs to be specified in LINUX_MAKE_ENV (so
it is exported and available in sub-processes of make). Any saved
configuration file would simply contain the reference to the
not-yet-expanded variable.
As in the Linux build system, the config variables are both read from
make as from a shell script, we cannot use $() syntax as this would be
interpreted as a command invocation by the shell. Instead, use ${}
syntax which is interpreted as variable reference both by the shell as
by make.
[Thomas:
- Really make the patch work by using $(LINUX_MAKE_ENV) instead of
$(TARGET_MAKE_ENV). Otherwise, the new BR2_BINARIES_DIR variable is
not passed at all stages of the build process, which makes the
build fail when an initramfs is used.]

When running 'make printvars', the output stops at the time we dump the
Linux related variables, with:
linux/linux.mk:109: *** Recursive variable `LINUX_TARGET_NAME'
references itself (eventually). Stop.
And that's expected, since we have:
109 LINUX_TARGET_NAME = $(LINUX_IMAGE_NAME)
[...]
112 ifeq ($(LINUX_IMAGE_NAME),)
113 LINUX_IMAGE_NAME = $(LINUX_TARGET_NAME)
114 endif
Even though they are defined in a way that ensures they are in fact not
recursively defined (the if-block ensures that), 'printvars' does dump
all our variables by evaluating all of them, which in that specific case
implies they are recursively defined.
Fix that by explicitly setting LINUX_IMAGE_NAME in each if-block.

The Buildroot coding style defines one space around make assignments and
does not align the assignment symbols.
This patch does a bulk fix of offending packages. The package
infrastructures (or more in general assignments to calculated variable
names, like $(2)_FOO) are not touched.
Alignment of line continuation characters (\) is kept as-is.
The sed command used to do this replacement is:
find * -name "*.mk" | xargs sed -i \
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*$#\1 \2#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\]\+\)$#\1 \2 \3#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\s*\([^\\ \t]\+\s*\\\)\s*$#\1 \2 \3#'
-e 's#^\([A-Z0-9a-z_]\+\)\s*\([?:+]\?=\)\(\s*\\\)#\1 \2\3#'
Brief explanation of this command:
^\([A-Z0-9a-z_]\+\) a regular variable at the beginning of the line
\([?:+]\?=\) any assignment character =, :=, ?=, +=
\([^\\]\+\) any string not containing a line continuation
\([^\\ \t]\+\s*\\\) string, optional whitespace, followed by a
line continuation character
\(\s*\\\) optional whitespace, followed by a line
continuation character
Hence, the first subexpression handles empty assignments, the second
handles regular assignments, the third handles regular assignments with
line continuation, and the fourth empty assignments with line
continuation.
This expression was tested on following test text: (initial tab not
included)
FOO = spaces before
FOO = spaces before and after
FOO = tab before
FOO = tab and spaces before
FOO = tab after
FOO = tab and spaces after
FOO = spaces and tab after
FOO = \
FOO = bar \
FOO = bar space \
FOO = \
GENIMAGE_DEPENDENCIES = host-pkgconf libconfuse
FOO += spaces before
FOO ?= spaces before and after
FOO :=
FOO =
FOO =
FOO =
FOO =
$(MAKE1) CROSS_COMPILE=$(TARGET_CROSS) -C
AT91BOOTSTRAP3_DEFCONFIG = \
AXEL_DISABLE_I18N=--i18n=0
After this bulk change, following manual fixups were done:
- fix line continuation alignment in cegui06 and spice (the sed
expression leaves the number of whitespace between the value and line
continuation character intact, but the whitespace before that could have
changed, causing misalignment.
- qt5base was reverted, as this package uses extensive alignment which
actually makes the code more readable.
Finally, the end result was manually reviewed.

The echo statements in the kconfig helpers are currently using double
quotes. For KCONFIG_SET_OPT this is problematic when the value argument
itself contains a double quote (a string value). In this case, the statement
echo "$(1)=$(2)" >> $(3)
would become:
echo "FOO="string value"" >> /some/path/.config
resulting in the string
FOO=string value
in the config file, rather than the properly quoted
FOO="string value"
The linux package worked around this by escaping the quote characters, but
a prettier solution is to use single quoting in the helpers (or
alternatively use no quoting at all).
A side effect of this change is that a $variable in the key or value would
no longer be interpreted by the shell, removing any unexpected behavior.
This change is only really necessary for KCONFIG_SET_OPT, but for symmetry
reasons the other helpers are updated too.
