Agreed, my question is whether or not adding the underscore is the
correct thing to do even if your architecture prepends an underscore
to symbol names? Is there a particular reason why this was done for
Blackfin, to make a particular app work? I am trying to find out what
the correct behaviour of dlsym is, for example does it behave like
this on other Unixes that have leading underscores on symbols.
