But we would need some solution in the meantime?

It might take some huge effort (and time) to convince the devs. Especially, since development is going towards LLVM ecosystem. Linus prefers compailing Linux with clang these days.

When the ABI handling works well, you could still use the same principles for package managment.

There are 2 main axis to work on, which are abysmally less costly than any container based mitigation of the issue, since with the following we get "clean" sets of ELF binaries:

- educate the devs on the matter. Those not using an engine already taking of that (this reduce by A LOT the amount of devs to teach).

- work on a toolchain switch to link with version symbol names from a backward ABI, easily (not having to manually enumerate all version symbol names and use the binutils gas .symver directive, or install a 10 years old distro). And a toolchain which does default to -static-libgcc, -static-libstdc++ (when c++ is used) and -ftls-model=global-dynamic while we are at it (in order to spare those expensive static TLS slots).

I do consider that gcc and clang(llvm) are lost for sane open source. Their absurd and grotesque size and complexity make them more toxic than anything else. Look at tinycc, cproc/qbe, simple-cc/qbe.
