In this case, linking statically is indeed an option.
We currently have little tooling for static libraries. Strictly speaking,
all statically linked libraries have to be rebuilt even for minor glibc
updates because we do not provide ABI compatibility for static linking
(there are no compatibility symbols, static binaries always get the most
Yep, I understand those caveats - the flipside is that most other Linux
distros already provide statically linked qemu user emulators with glibc
without suffering unduly. So while I accept there are potential problems,
it doesn't seem like they're frequent / severe enough to make this approach
