You can build libbacktrace against musl and it should work. The
functionality is not provided in musl because it requires a great deal
of machinery that most users don't need, that has no reason to be
intertwined with libc, and that makes it impossible to bootstrap a
toolchain and library ecosystem efficiently (since there would be a
circular dependency between the unwind library code and libc).
