Is there an update on these failures?
I have also seen these failures and have not understood the cause.

Will this fix be backported to GCC 12 and GCC 11 ?

Bug ID: 107620
   Summary: Build errors when using sphinx
   Product: gcc
   Version: unknown

  Severity: normal

I am noticing errors with use of sphinx when building:
Build machine: x86_64-none-linux-gnu

Target: aarch64-none-elf or arm-none-eabi

Is the above error due to not installing sphinx 5.3.0?
I assumed installing sphinx 5.3.0 would help, but after installing sphinx
5.3.0, I get a different error:

Extension error:
Could not import extension gcc_sphinx (exception: No module named 'gcc_sphinx')

Hi Jonathan, 

I see that you plan to fix this soon
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=103570#c1), and thank you for
that. Do you have a rough estimate of when we would see a fix for this? One of
our releases depends on a fix for this issue.

Kind regards
Vasee

Hi Christophe, if you are working on this, just wondering whether we are close
