The problem is not with "modern" executables that are properly annotated with

My objection is to the intentional breaking of old executables that have no
PT_GNU_STACK annotation, but require an executable stack. Since we usually
try not to break userspace, we cannot merge a patch like this one.
How old are these and how many are still around?
As far as I can determine, no official GCC release defaults to
generating PT_GNU_STACK for MIPS, I could be mistaken though. So to
answer your questions: Very young, and all of them.
Can the annotation be added with a tool?
I don't know, although I seem to recall that such a tool existed, and I
may have even used it in the past. But, my google fu is not
sufficiently advanced to find it now, if it exists.
