Subject: v5.17-rc3 compile failure on aarch64

Hi,

Recently I found v5.17-rc3 kernel failed to compile on my aarch64 setup,
it failed with the following error messages:

   AR      lib/zstd/built-in.a
   LD [M]  lib/zstd/zstd_compress.o
ld: __patchable_function_entries has both ordered
[`__patchable_function_entries' in lib/zstd/common/entropy_common.o] and
unordered [`__patchable_function_entries' in
lib/zstd/common/error_private.o] sections
ld: final link failed: bad value
make[2]: *** [scripts/Makefile.build:484: lib/zstd/zstd_compress.o] Error =
1
make[1]: *** [scripts/Makefile.build:550: lib/zstd] Error 2
make: *** [Makefile:1831: lib] Error 2
make: *** Waiting for unfinished jobs....

But the same code base compiles fine inside my x86_64 VM.

The aarch64 environment is an VM running on RockPro64 or RPI CM4.

With a little older gcc (v10.2.0) and bintuils (2.35).

While for my x86_64 VM it has newer gcc (11.1.0) and binutiles (2.36.1)

I'm super happy to upgrade my tool chain for my aarch64 VM, but I'm a
little concerned if there is something worthy fixed.

Thanks,
Qu
