           Summary: toolchain Arm AArch64 toolchain 11.2-2022.02
           Product: buildroot
           Version: unspecified
          Hardware: All
                OS: Linux

  Target Milestone: ---

Hello,

I'm using the current Buildroot master branch after the 2022.08 release and
after the merge of the next branch that include a ARM toolchain version bump to
11.2-2022.02.

This toolchain trigger some "Illegal instruction" error on some x86_64 host
like Intel(R) Xeon(R) CPU X5670.

gfortran is not able to pass the check in helper.mk:

<built-in>: internal compiler error: Illegal instruction
0x7f42c83efd5f ???
        ./signal/../sysdeps/unix/sysv/linux/x86_64/sigaction.c:0
0x7f42c83dad09 __libc_start_main
        ../csu/libc-start.c:308
Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.

Disabling gfortran allows to continue the build but it break with busybox build
with similar errors:

It happen with the arm and aarch64 target.

Tested with Intel(R) Core(TM) i7-10850H cpu doesn't trigger such problem.

Best regards,
