Kernel headers versions 3.6.x and 3.7.x have been deprecated since 2013.05
and thus can be removed in 2014.05.
An automatic selection of 3.8.x headers is performed in the legacy menu.
An existing automatic selection of 3.6.x headers is modified to select
3.8.x.
As this patch removes the last occurrances of BR2_DEPRECATED_SINCE_2013_05,
the symbol is removed too.

In commit 971e331c54
('package/linux-headers: remove 2.6 snapshot'), we removed the support
for the Linux headers snapshot option, but we forgot to remove some
related help text in the main Config.in option of the Linux headers
package.

Old toolchains, with old gcc that do not support -print-sysroot, break the
kernel-headers version check script: it fails to find the sysroot of the
toolchain, and thus ends up including the host's linux/version.h.
Most of the time, this will break early, since the host's kernel headers
will not match the toolchain settings.
But it can happen that the check is succesful, although the configuration
of the toolchain is wrong:
- the custom toolchain has kernel headers vX.Y
- the user selected vX.Z (Z!=Y)
- the host has headers vX.Y
In this case, the check passes OK, but the build of some packages later on
will break (which is exactly what those _AT_LEAST_XXX options were added to
avoid).
Fix that by passing the sysroot to the check script, instead of the cross
compiler.
We get the sysroot as thus:
- for custom toolchains, we use the macro toolchain_find_sysroot. We can
do that, because we already have a complete sysroot with libc.a at that
time.
- for internal toolchain using a custom kernel headers version, we just
use $(STAGING_DIR). We can't use the macro as for custom toolchains
above, because at the time we install the kernel headers, we do not yet
have a complete sysroot with a libc.a. But we can just use
$(STAGING_DIR), since we're only interested in the kernel headers.
For all other types of toolchains, we already have the _AT_LEAST_XXX options
properly set, so we need not add a check in this case.

Select the appropriate BR2_TOOLCHAIN_HEADERS_AT_LEAST_XXX options for the
internal toolchain backend.
For the manualy-specified version, we bring up the choice that sets the
_AT_LEAST_XXX symbols.
[Thomas: rename symbols from BR2_PACKAGE_HOST_LINUX_HEADERS_<version>
to BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_<version> to clearly indicate
that they are used to specify the version of custom headers.]

As Thomas states:
It is completely weird to ask the tarball to be named exactly
linux-2.6.tar.bz2. IMO, we should simply get rid of this feature.
Make it so! ;-)

For some architectures (eg. Arc, Cris, Hexagon, ia64, Parisc, Score and
Xtensa), the Linux buildsystem tries to call the cross-compiler when
installing the headers.
This is a spurious call, since a cross-compiler is not needed at all to
install the headers.
As some users have reported the issue, just add a comment in linux-headers.mk
directing the user to ignore those errors.

3.3.8 support is removed since 334dca61 (kernel-headers: remove deprecated
versions 3.1, 3.3, 3.5), so let's get rid of the patch as well.

This commit makes the dependency from the target toolchain explicit.
This way we can buid from command line a package that use
inner-generic-package right after the configuration phase, example:
make clean <package-name>
Also remove TARGETS_ALL because the only purpose was to add toolchain
dependency so it's superseded by this commit.
To prevent circular dependency add the new variable
<pkgname>_ADD_TOOLCHAIN_DEPENDENCY to avoid adding the toolchain
dependency for toolchain packages.
This is also a step forward supporting top-level parallel make.

The Linux kernel headers versions 3.1, 3.3, and 3.5 have been deprecated
since 2013.02 and thus can be removed in 2014.02.
For legacy handling, we automatically select versions 3.2, 3.4, and 3.6,
respectively.
Additionally, this patch removes the now unused symbol
BR2_DEPRECATED_SINCE_2013_02.

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.

Some Config.in(.host) files have constructs like:
config FOO_VERSION
string
default "1.0" if FOO_1_0
default "2.0" if FOO_2_0
default $FOO_CUSTOM_VERSION if FOO_CUSTOM
The dollar sign here is not needed and confusing, so can be removed.
