I don't really intend to implement secure-plt any time soon on sparc
because there simply is no way to do it efficiently.

And when you talk about "toolchain issues" that all goes my way
anyways, so just direct such queries to me directly since I handle
both the kernel and toolchain bits entirely myself these days.

So you'll always have to deal with the PLT section on sparc having
write and execute permission.
