MIPS: add .note.GNU-stack section to assembly sources (#872)

To build ELF shared libraries that do not require executable stack on
MIPS, every object file linked should have a .note.GNU-stack section,
otherwise the linker defaults to executable stack.

As libffi shouldn't require executable stack, add the .note.GNU-stack
section to the assembly source files under src/mips, like other
architectures.
