Currently, the kconfig part contains two things: the kconfig option
with the paths to br2-external trees, and the kconfig menus for the
br2-external trees.
When we want to include more kconfig files from the br2-external tree
(e.g. to get definitions for pre-built toolchains), we will need to
have the paths defined earlier, so they can be used from the br2-external
tree to include files earlier than the existing menus.
Split the generated kconfig file in two: one to define the paths, which
gets included early in our main Config.in, and one to actually define
the existing menus, which still gets included at the same place they
currently are.

In commit 7484c1c3b8 (toolchain/toolchain-wrapper: add BR2_RELRO_),
we added the PIC/PIE flags, but based on the RELRO_FULL condition.
It is however totally possible to do a PIC/PIE executable without
RELRO_FULL, as it is also valid to do a PIC/PIE build with RELRO_PARTIAL.
Add a new option that now governs the PIC/PIE flags.
Note: it is unknown if RELRO_FULL really needs PIC/PIE or not, so we
keep the current situation, where RELRO-FULL forces PIC/PIE compilation.
Decoupling can come later from an interested party.

Currently, use of -fstack-protector-strong is only available for gcc
starting with 4.9, on the assumption that it appeared with that version.
Although this is true, it happens that quite a few vendors will have
back-ported -fstack-protector-strong to older gcc versions (at least 4.8
seen in the wild).
Remove the guard against gcc>=4.9, and expand the help text.
Note: we could have changed the guard to something like:
depends on BR2_TOOLCHAIN_GCC_AT_LEAST_4_9 || BR2_TOOLCHAIN_EXTERNAL_CUSTOM
However, the latest gcc we support in the internal toolchain now *is*
gcc-4.9, and similarly all external toolchains except Sourcery ARM are
4.9 or higher. So except for the Sourcery toolchain, the condition would
have always been true. For that one toolchain, we can allow it to hit
the SSP check, and just drop the condition entirely.

Currently, that file is generated rather late in the configuration
process, so BUILD_DIR is known (and exists) by then.
We're soon to generate that file much earlier, at a point where
BUILD_DIR is not yet known, so we have two options:
1- declare BUILD_DIR earlier;
2- generate the file in an already-known location.
We go with the second solution, as we're already generating a
br2-external related file in BASE_DIR, so we can as well generate all
br2-external files in the same place.

Currently, we repeat all the SSP level selection deep down to the
toolchain wrapper itself, where we eventually translate it to the
actual SSP option to use. This is a bit redundant.
Additionally, we will want to check that the toolchain actually
supports that option (for those toolchain where it was backported).
So, move the translation into kconfig, and add the qstrip'ed value
to the additional flags passed to the wrapper. Add it before
user-supplied opitons, to keep the previous behaviour (and allow
anyone crazy-enough to override it with BR2_TARGET_OPTIMIZATION).

This commit adds a config option which will force buildroot to
build all host dependencies even if they are already present on the
host system. This may be a desirable option if different hosts are
used to build the same source. In this case, some packages will be
built on one host that are not built on another. This is problematic
if build source archives are cached afterwards for offline builds.

When we do a release, we know only of a set of gcc versions that the
host may have. But in the future, distributions with newer gcc versions
may show up.
Currently, we do not recognise those versions, and thus we do as if they
were older than the oldest we know of. This means that a set of packages
become unselectable, when they should be.
We fix that by capping the detected version to the highest we know of.

Starting with version 7, gcc automatically recognises and enforces the
environment variable SOURCE_DATE_EPOCH, and fakes __DATE__ and __TIME__
accordingly, to produce reproducible builds (at least in regards to date
and time).
However, older gcc versions do not offer this feature.
So, we use our toolchain wrapper to force-feed __DATE__ and __TIME__ as
macros, which will take precedence over those that gcc may compute
itself. We compute them according to the specs:
https://reproducible-builds.org/specs/source-date-epoch/https://gcc.gnu.org/onlinedocs/cpp/Standard-Predefined-Macros.html
Since we define macros otherwise internal to gcc, we have to tell it not
to warn about that. The -Wno-builtin-macro-redefined flag was introduced
in gcc-4.4.0. Therefore, we make BR2_REPRODUCIBLE depend on GCC >= 4.4.
gcc-7 will ignore SOURCE_DATE_EPOCH when __DATE__ and __TIME__ are
user-defined. Anyway, this is of no consequence: whether __DATE__ and
__TIME__ or SOURCE_DATE_EPOCH takes precedence, it would yield the
exact same end result since we use the same logic to compute it. Note
that we didn't copy the code for it from gcc so using the same logic
doesn't imply that we're inheriting GPL-3.0.

The BR2_DEPRECATED logic is a lot less useful than the legacy handling,
because the symbols just disappears without warning to the user. For
example, we had a few defconfigs that were using deprecated symbols
(which were not actually used because BR2_DEPRECATED wasn't set) so
these didn't build the expected code anymore.
Also, the idea behind BR2_DEPRECATED is that you can easily revive it
again if there is interest. However, it is relatively easy to revert
the removal of a package as well.
The deprecation is also more effort because it has to be removed twice:
once when deprecating, and once when really removing.
It doesn't make sense to add a legacy entry for BR2_DEPRECATED. Users
who actually used it will get legacy warnings instead.
