ba4ad9d27c deprecated handling: introduce BR2_DEPRECATED_SINCE_xxxx_xx
In order to keep better track of when a feature got deprecated, and hence
when it can be removed, a new set of symbols BR2_DEPRECATED_SINCE_xxxx_xx is
introduced. These symbols are automatically selected when BR2_DEPRECATED is
selected, and thus are transparent to the user.
A deprecated feature will no longer depend on BR2_DEPRECATED directly, but
rather on the appropriate BR2_DEPRECATED_SINCE_xxxx_xx. If that symbol does
not yet exist, it has to be created in Config.in.
When removing a deprecated feature, one should also check whether this was
the last feature using the BR2_DEPRECATED_SINCE_xxxx_xx symbol, in which
case the latter can be removed from Config.in.

A followup patch will make sure the overview is added to the list of
deprecated features in the manual, so that a buildroot core developer can
easily determine which features to remove in a given development cycle.

269da64af5 package: deprecate some more development tools
Since some time, we have removed the support to build a toolchain for
the target, and therefore the support for several development tools on
the target.

This commit deprecates a few additional development tools: m4, bison,
flex and gob2. For flex, we retain the ability to build libfl, we only
deprecated the ability to build the flex binary itself.

The original motivation for this patch is that m4 is causing build
issues in some configurations, but there isn't really much incentive
to fix this package for the target, since it is not really useful for
embedded Linux systems.

Bison, Flex and Gob2 are deprecated because they are reverse
dependencies of m4.

be084204eb Config.in files: add missing dependencies to toolchain option comments
When a package A depends on config option B and toolchain option C, then
the comment that is given when C is not fulfilled should also depend on B.
For example:

config BR2_PACKAGE_A
	depends on BR2_B
	depends on BR2_LARGEFILE
	depends on BR2_WCHAR

comment "A needs a toolchain w/ largefile, wchar"
	depends on !BR2_LARGEFILE || !BR2_WCHAR

This comment should actually be:

comment "A needs a toolchain w/ largefile, wchar"
	depends on BR2_B
	depends on !BR2_LARGEFILE || !BR2_WCHAR

or if possible (typically when B is a package config option declared in that
same Config.in file):

if BR2_B

comment "A needs a toolchain w/ largefile, wchar"
	depends on !BR2_LARGEFILE || !BR2_WCHAR

[other config options depending on B]

endif

Otherwise, the comment would be visible even though the other dependencies
are not met.

This patch adds such missing dependencies, and changes existing such
dependencies from
  depends on BR2_BASE_DEP && !BR2_TOOLCHAIN_USES_GLIBC
to
  depends on BR2_BASE_DEP
  depends on !BR2_TOOLCHAIN_USES_GLIBC
so that (positive) base dependencies are separate from the (negative)
toolchain dependencies. This strategy makes it easier to write such comments
(because one can simply copy the base dependency from the actual package
config option), but also avoids complex and long boolean expressions.

51788521b7 libglib2: needs threads
This commit adds a dependency of the libglib2 package on thread
support in the toolchain, since upstream libglib2 doesn't build
without thread support. The commit is rather large as it involves
propagating the dependency on thread support to all reverse
dependencies of the libglib2 package.

[Thomas: squash all patches into one, make a few minor fixes, the most
important one being to not add comments about MMU requirement when a
package doesn't work on !MMU platforms.]

e265a1fa05 packages/flex: remove unnecessary BR2_PACKAGE_FLEX_LIBFL
The BR2_PACKAGE_FLEX_LIBFL knob was removed by
bd72a13a4c so remove it from the packages
that used it since it's completely unnecessary.

b730010c90 package: gettext needs WCHAR support
gettext needs WCHAR support in the toolchain, and as libglib2 depends on
gettext and lots of stuff depends on libglib2, quite a lot of packages
needs to have their dependencies adjusted.

program at compile time) and flex on the target (so that it can link
