Description: fix mod_loader on HPPA
 The problem is dlsym returns a function pointer on hppa when passed the name
 of a function symbol.  It points at a function descriptor for the function
 when the plabel bit is set in the pointer.  The descriptor has an entry which
 points at the function after it has been bound.  Otherwise, it points at
 trampoline code to fix up the descriptor.
 .
 In any case, dladdr doesn't do the expected thing when passed a function
 pointer.  It needs the actual address of the function.
 .
 The attached patch fixes the build on hppa-linux.  Another option would be to
 adjust the configure check.
