Building the target google-breakpad requires building the host variant
of google-breakpad. Just like the target google-breakpad only supports
a limited number of architectures, it is the same for the host
google-breakpad.
We therefore introduce a
BR2_PACKAGE_HOST_GOOGLE_BREAKPAD_ARCH_SUPPORTS option that is used
where necessary to prevent the user from choosing Google Breakpad when
building on unsupported host platforms.

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.

Curently, we have a choice to select between stripping and not
stripping. This is legacy code from back when we had a third option,
sstrip (super-strip).
Since we removed sstrip, stripping or not stripping is now just a
boolean rather than a choice.
Make it so.
We make BR2_STRIP_strip default to 'y' to keep the current behaviour of
defaulting to stripping.
Move BR2_STIP_none to legacy, and instruct the user to review the new
setting.

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.
