As reported to Linaro bug tracker [1] the Arm GNU Toolchain generated
since 2022.02 doesn't work on all x86_64 host.
It still not fixed with 11.3.Rel1 release (2022.08).

Currently, glibc depends on !BR2_STATIC_LIBS in all the toolchain
variants.
However, for some architectures, glibc is the only supported libc. In
commit 3b3105328e ("Config.in: only
allow BR2_STATIC_LIBS on supported libc/arch"), we implemented a fix
to avoid configurations were BR2_STATIC_LIBS=y with an architecture
already supported by glibc, because these configurations are
impossible. This commit 3b3105328e
prevents from selecting BR2_STATIC_LIBS=y when the C library used for
the internal toolchain backend is glibc.
However, it introduces a discrepency between how this topic is handled
for internal and external toolchains:
- For internal toolchains, we prevent BR2_STATIC_LIBS=y if glibc is
chosen.
- For external toolchains, we allow BR2_STATIC_LIBS=y in all cases,
and it's each glibc toolchain that has !BR2_STATIC_LIBS
This commit addresses this discrepency by preventing BR2_STATIC_LIBS=y
if glibc is chosen in all cases.
Thanks to this, we can remove the !BR2_STATIC_LIBS dependency on both
the glibc package, and all glibc external toolchains.

[Thomas: update to master, fix the gen-bootlin-toolchains script, add
a comment in the static/shared choice to indicate that static is
supported only with uclibc or musl]

Update to gcc 10.3, gdb 10.2, binutils 2.36.1, glibc 2.33.
Remove BR2_TOOLCHAIN_HAS_NATIVE_RPC since the support for obsolete
RPC was finally dropped in glibc in 2.32 (2020-08-04).

>From [1]:
* All GCC 8.2 features. For details on GCC 8 release series.
* Linaro specific pre-processor macros to ensure that this is a
continuation from the Linaro releases.
* Spectre v1 mitigation backport from upstream FSF trunk include the
revisions. This is an initial backport of those mitigations in
the GNU toolchain and should be regarded as support for prototyping
and early access only. Moreover, while the backports include support
for the other architectures, they are included for completeness and
all issues regarding these patches must be taken up upstream in the
https://gcc.gnu.org/bugzilla by reproducing the same with upstream
FSF trunk.
Arm is interested in feedback regarding these workarounds for
Spectre v1.
A description of the mitigation has been published on LWN.net.

This is the same toolchain that was previously distributed by Linaro. [1]
Switch default toolchain as this toolchain supersed the Linaro AArch64 toolchain.
Only x86_64 host are supported, so keep Linaro toolchain for x86 host.
Tested with qemu_aarch64_virt_defconfig.
