Building glibc for many different configurations and running the

elf/check-execstack test for hppa, ia64 and microblaze.
ia64 is non-execstack by default, so it doesn't need any marking. The
same is true for every architecture that doesn't override
elf_read_implies_exec, which includes microblaze and hppa.
This fails because those configurations are not generating
.note.GNU-stack sections to indicate that programs do not need an
executable stack.
This needs to be fixed in glibc.
The requirement that a null .note.GNU-stack section needs to be defined
to indicate that the default stack (i.e., non-executable) is used seems
backward.
I don't have any problem approving the MicroBlaze GCC changes, but, like
Andreas, I think that this is a glibc problem.
