[musl] Question: dladdr alternative for symbol info lookup with full static linking

[Amine Chikhaoui]

Hello,

I posted this question on #musl irc a week or so ago, but I don't think
anyone noticed so trying the mailing list instead:

>> I have a C++ project that I'm trying to statically link using musl.

Just looking for any alternatives for doing something similar in order
to print a useful stacktrace when in a statically linked binary context.
