.mk files: bulk aligment and whitespace cleanup of assignments
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.

dependencies: add function suitable-host-package
Sometimes, buildroot needs a certain host tool to do its job, e.g. tar. In
many cases, we expect this tool to be present on the host system, but this is
not always the case. Or maybe, the version on the host system is not
suitable, and we need a more recent one.
In some of these cases, instead of bailing out, buildroot could build the
package first (but only if the existing system package is not suitable).
To aid in detecting if a host package is suitable or not, this patch adds a
function suitable-host-package. When called with parameter foo, it will
execute check-host-foo.sh. This script should return either the path to the
suitable host package, or the empty string if no suitable package can be found.
The rules to determine whether something is suitable or not is left to
check-host-foo.sh and depends on foo.
An example usage of suitable-host-package is:
DEPENDENCIES_HOST_PREREQ += $(if $(call suitable-host-package,foo),,host-foo)
To avoid cluttering the existing dependencies.mk file, it includes any
check-host-foo.mk file. These files can be used to hold appropriate
dependency-related actions for foo.
