* config/pa/tm-hppa.h (EXTRACT_RETURN_VALUE): Handle software 

floating point correctly.
        (STORE_RETURN_VALUE): Likewise.
        * config/pa/tm-pro.h (SOFT_FLOAT): define.
Fixes minor testsuite failures for pro targets.

/* For some stupid reason find_pc_partial_function wants to treat
trampoline symbols differently.
In a nutshell, find_pc_partial_fucntion sets the low address for
the function to the PC value that was passed in if the PC value
passed in is a mst_trampoline symbol.
This causes wait_for_inferior to execute code for stepping over
or around a function (stop_pc == stop_func_start). This is
extremely bad when we're stepping through a return from a shared
library back to user code (which on the PA uses trampolines). */
