pru: bfd: Correct default to no execstack
Data and instruction memories are strictly separated, so it is not
possible to execute instructions from the stack memory on PRU.
I don't see any difference in testsuite results with or without this
change.
bfd/ChangeLog:
* elf32-pru.c (elf_backend_default_execstack): Define as 0.
ld/ChangeLog:
* testsuite/ld-elf/elf.exp (target_defaults_to_execstack):
Return 0 for pru.
