08506501b0 flex: change config text of 'target binary' option
The buildroot manual contains a list of deprecated items, with their config
title text, and the location in the config menu. If the config text does not
mention a package name, this can be confusing.

For example, the symbol BR2_PACKAGE_FLEX_BINARY has as text:
'Install tool in the target', which outside of the flex context makes no
sense at all.

To make sure the deprecated packages list in the manual is understandable,
rename the (deprecated) flex 'target binary' config option.

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.

c0d30d4c94 flex: propagate m4 dependency on wchar
Commit fe6a9e5e9d missed the fact that
m4 has a dependency on wide char support, so this dependency should be
propagated to flex.

Fixes:

fe6a9e5e9d flex: needs M4 at runtime
For proper runtime execution, flex requires m4 to be
installed. Passing a M4 variable at configure time is needed,
otherwise flex on the target will try to use a 'm4' binary with a
build machine path.

Fixes bug #4988.

bd72a13a4c flex: fix build for nommu systems
The flex binary uses fork() so it breaks on !MMU builds.
Since we usually don't require flex in the target and the common
scenario is that we just want libfl in staging reverse the options so
that BR2_PACKAGE_FLEX just builds and install libfl.a and change the
LIBFL option to BR2_PACKAGE_FLEX_BINARY to install the binary in the
target.
