Subject: MIPS: add .note.GNU-stack section to assembly sources (#872)
X-Git-Tag: upstream/3.4.7~7
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f515eac04cf8e5f594d5d9dee5fb7dfc3a186a4c;p=platform%2Fupstream%2Flibffi.git

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.
