cris: bfd: Correct default to no execstack
In the now-historical CRIS glibc port, the default stack permission
was no-exec as in "#define DEFAULT_STACK_PERMS (PF_R|PF_W)", and the
gcc port only emits the executable-stack marker when needed; when
emitting code needing it. In other words, the binutils setting
mismatches. It doesn't matter much, except being confusing and
defaulting to "off" is more sane.
ld:
* testsuite/ld-elf/elf.exp (target_defaults_to_execstack): Switch to 0
for cris*-*-*.
bfd:
* elf32-cris.c (elf_backend_default_execstack): Define to 0.
