Currently we rely on the dynamic symbol table to generate stack traces.
This only works with exported functions of an executable (i.e.
visibility=default) and requires the -L--export-dynamic argument.

One alternative would be to use DWARF instead. It would also allow to get line
numbers, but is only available in debug builds.

A better compromise might be to provide MiniDebugInfo which is a compressed
symbol table in .gnu_debugdata.
