Subject: [PATCH] build SDL with nonexecutable stack
libSDL is by default marked with an executable stack, which it doesn't
actually need. the reason for this is that there are assembler files in the
source tree not properly annotated with the "noexec stack" section. As such
the linker does a safe-fallback and marks the whole lib as "requires
executable stack".
the patch below removes this by adding annotations. As far as I can see it
shouldn't break anything.
