In preparation of adding a new kernel-type, Yann D. came up
with a change in semantic on binutils/gold availability.
So far, it was architectures' responsibility to declare that
they did support binutils/gold or not. It makes much more sense
that binutils/gold declares its own availability depending on
the current architecture; after all, architectures have no way
to know wether gold supports them, while gold does know it.

binutils 2.21 doesn't recognise the Cortex-M3 SVC instruction when
assembling with -mcpu=all. This was fixed by the 2.21.53 snapshot and
is needed to build RTOSs such as FreeRTOS.

Recently, all binutils versions have been renamed after a GPL compliance
issue was found and fixed in binutils;

Although legacy symlinks have been put in place, we should now use
the new, real version strings.

Old versions are no-longer available since the rename (eg. 2.19 has been
superseeded by 2.19.1, and only 2.19.1a was regenerated).
Remove now-missing versions.

This patch makes binutils benefit from the TOOLCHAIN_PKGVERSION and

kconfig bools are disabled by default, so specifying 'default n' is useless and
noisy. This patch removes all occurrences of 'default n'.

Update help entries for thos variables that accept multiple
arguments with spaces (aka. array-capable variables).
Signed-off-by: "Yann E. MORIN" <yann.morin.1998@anciens.enib.fr>
Make it explicit that a variable is an array bu the name of the variable.
It will be used later when .config gets munged to allow both multiple
arguments and arguments with spaces at the same time to be passed from the
configuration down to the build scripts.

gold is not capable of building glibc/eglibc, so we have to
force using the BFD linker, ld.bfd.
Offer a blind option that affected components can select to
force use of the BFD linker during the build.

The gold linker does currently support only a limited set of architectures:
- x86 (32- and 64-bit)
- ARM
Hide the gold option for other architectures.

Plugins are shared objects, and when building a toolchain statically,
the gcc build system breaks havok (although there is no hard technical
reasons it should not be possible)...
And consequently, do not enable plugin supoprt in binutils.

When both gold and ld are installed, add a wrapper that calls
to either gold or ld.
In case the wrapper is installed, we also need to symlink ld.bfd
and ld.gold for the core_cc steps.

When configured with support for threads, gold can link in
parallel, possibly cooperating with a make jobserver.
Add an option enabling threads.

gold is a new, optimised, multi-threaded linker with support
for plugins.
Add support for gold starting with binutils 2.21. Although 2.20
also had gold, the configure flags have changed, and supporting
2.20 would be a mess in the code.

Add BINUTILS_2_21_or_later blind option. It will be used to add
conditional support for building 'gold' on versions that have it.

The companion libraries on the target are required only for internal use by
binutils and gdb. The user should not have to know about this, so hide the
option.
