Gcc bug 99140 has been fixed on gcc 8.x but reappeared on gcc 9.x while
it's been fixed on gcc 10.x+. So let's update
BR2_TOOLCHAIN_HAS_GCC_BUG_99140 accordingly.

This bug has been fixed upstream and backported to buildroot binutils
package. So let's remove it from toolchain/Config.in and from packages
that are affected by it:
- libgeos
- postgis
- protobuf

BR2_TOOLCHAIN_HAS_BINUTILS_BUG_20006 options were last selected by the
BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_AMD64 toolchain, but this
toolchain has been removed as part of commit
d87e114a8f in August 2020.

The OpenRISC binutils is affected by a linker bug (binutils bug 21464)
for which no workaround exists. This causes build breakage in a number
of packages, so this commit introduces a
BR2_TOOLCHAIN_HAS_BINUTILS_BUG_21464 option to identify this bug. As
all binutils versions are affected, this option is true whenever the
configuration targets OpenRISC.
The bug was already reported and it's been recently updated:

This will allow toolchain to indicate if they support
-fstack-protector-strong or not.
Whenever the gcc version is >= 4.9, we always have SSP_STRONG support
if we have SSP support. However, some toolchains older than gcc 4.9
might have backported SSP_STRONG support, which is why we cannot rely
just on BR2_TOOLCHAIN_GCC_AT_LEAST_4_9.
Having this "default" value allows to avoid adding a "select
BR2_TOOLCHAIN_HAS_SSP_STRONG" in the internal toolchain logic plus in
almost external toolchains. But it allows custom external toolchains
that are pre-4.9 to potentially declare that they support strong SSP.

When Buildroot is released, it knows up to a certain kernel header
version, and no later. However, it is possible that an external
toolchain will be used, that uses headers newer than the latest version
Buildroot knows about.
This may also happen when testing a development, an rc-class, or a newly
released kernel, either in an external toolchain, or with an internal
toolchain with custom headers (same-as-kernel, custom version, custom
git, custom tarball).
In the current state, Buildroot would refuse to use such toolchains,
because the test is for strict equality.
We'd like to make that situation possible, but we also want the user not
to be lenient at the same time, and select the right headers version
when it is known.
So, we add a new Kconfig blind option that the latest kernel headers
version selects. This options is then used to decide whether we do a
strict or loose check of the kernel headers.

This patch extends the "copy extra GCC libraries to target" feature to
also work for internal toolchains. The variable has been renamed to be
BR2_TOOLCHAIN_EXTRA_LIBS and the configuration option moved under the
generic toolchain package. For external toolchains, the step that does
the copy is still in the copy_toolchain_lib_root() helper which copies
from the sysroot to the target. For the internal toolchain, the host
gcc-final package does a post install hook to copy the libraries from
the toolchain build folders to both the sysroot and target(!static).
Examples where this can be useful is for adding debug libraries to the
target like the GCC libsanitizer (libasan/liblsan/...).

dmalloc and fxload fail to build for the Microblaze architecture with
optimization enabled with gcc < 8.x, with the following failure:
Error: PC relative branch to label logerror which is not in the instruction space
Error: operation combines symbols in different segments
The following defconfig allows to reproduce the issue:
BR2_microblazeel=y
BR2_OPTIMIZE_2=y
BR2_KERNEL_HEADERS_5_0=y
BR2_GCC_VERSION_7_X=y
BR2_PACKAGE_FXLOAD=y

gcc 8.x.

GCC uses thunk functions to adjust the 'this' pointer when calling C++
member functions in classes derived with multiple inheritance.
Generation of thunk functions requires support from the compiler back
end. In the absence of that support target-independent code in the C++
front end is used to generate thunk functions, but it does not support
vararg functions.
Support for this feature is currently missing in or1k and xtensa
toolchains.
Add hidden option BR2_TOOLCHAIN_SUPPORTS_VARIADIC_MI_THUNK that
indicates presence of this feature in the toolchain. Add dependency to
packages that require this feature to be built.
