Building pantry-sfu fails with g++ version diff or musl

[vicariousdrama]

This issue is not specific to Corny Chat, but also applies to current builds of Jam. Jam Issues do not note this problem yet.

It would seemingly work with version 12 of g++

See last success: https://gitlab.com/jam-systems/jam/-/jobs/5531981278

• musl 1.2.4-r2 on line 68
• version 12.2.1_git20220924-r10 is used for libgomp, libstdc++-dev, libatomic, gcc, g++

And failures since
https://gitlab.com/jam-systems/jam/-/jobs/6065177821

• version 13.2.1_git20231014-r0 is used for libgomp, libstdc++-dev, libatomic, gcc, g++

Example failure begins around line 767 of build logs related to abseil-cpp-20211102.0
