Thanks for filing this! The failing test is a symbol visibility check to
check that no unwanted symbols are being exported. Basically we check
that we only export the symbols from `phosh-exported-symbols.txt`) which
looks like:

{
   phosh_shell_get_default;

   …

   gtk_filter_list_model_*;
   gtk_sort_list_model_*;
};

Matthias do you have an idea why all the symbols are visible on the
above three architectures but not on others although we don't use
`--export-dynamic`?

This is the relevant linker line from the log at:
