symbol information, which reports this guy as a stub.
(FIXME): Unfortunately, we are not that lucky: it turns out that the
partial symbol information is also wrong sometimes. This is because
when it is entered (somread.c::som_symtab_read()) it can happen that
if the type of the symbol (from the som) is Entry, and the symbol is
in a shared library, then it can also be a trampoline. This would
be OK, except that I believe the way they decide if we are ina shared library
does not work. SOOOO..., even if we have a regular function w/o trampolines
its minimal symbol can be assigned type mst_solib_trampoline.
Also, if we find that the symbol is a real stub, then we fix the unwind
