[Tests] NFC: XFAIL test/Interop/Cxx/stdlib/libstdcxx-module-interface…

[xedin]

….swift

The test started crashing in linux-aarch64 configuration in CI.

[xedin]

For reference the build is - https://ci.swift.org/job/oss-swift-package-debian-12-aarch64/1039

[xedin]

@swift-ci please smoke test

I have a potential fix PR here: #80925

Though, PR testing isn't exercising this failure, so I can't be 100% sure it fixes the problem. Would it be possible to wait with the XFAIL until I merge the potential fix (in a couple hours after PR testing is done) and then only if that doesn't work, proceed with the XFAIL?

[xedin]

@kubamracek Sure!

[kubamracek]

Thanks! Let's check in the morning if it addresses the issue or not :)

[kubamracek]

FYI the failure also shows up on https://ci.swift.org/job/oss-swift-RA-linux-ubuntu-22_04/, which presumably runs a bit more often than the packaging job.

[kubamracek]

Looks promising: One of the jobs turned green, the other is now running.

[kubamracek]

Aaand https://ci.swift.org/job/oss-swift-package-debian-12-aarch64/ is green too, now :)

[xedin]

Awesome!

[xedin]

Thank you for looking into this so quickly!
