⚠️⚠️⚠️ Buildbot failure ⚠️⚠️⚠️

Hi! The buildbot aarch64 RHEL8 LTO + PGO 3.x has failed when building commit 1eb3ade.

What do you need to do:

1. Don't panic.
2. Check the buildbot page in the devguide if you don't know what the buildbots are or how they work.
3. Go to the page of the buildbot that failed (https://buildbot.python.org/#/builders/78/builds/8420) and take a look at the build logs.
4. Check if the failure is related to this commit (1eb3ade) or if it is a false positive.
5. If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.

You can take a look at the buildbot page here:

https://buildbot.python.org/#/builders/78/builds/8420

[FFY00]

The buildbot failure seems unrelated.

[colesbury]

The target path here is wrong so this gets re-run for every invocation of make.

[merwok]

@FFY00 was this addressed since?

[rgommers]

This logic is wrong. Whether libpython.so is shipped and must be linked against is very much not the same as whether extension modules are supported. The default builds on Linux and macOS do not require linking against libpython. On a regular 3.14 install on 64-bit Linux:

>>> import sysconfig
>>> sysconfig.get_config_var('LDLIBRARY')
'libpython3.14t.a'
>>> sysconfig.get_config_var('LIBPYTHON')
''

I'll open a new issue.
