[PATCH] D17918: [ELF] - Issue an error if trying to generate relocatable from objects having mixed splitstacks.

[George Rimar via llvm-commits]

Each object file compiled in split stack mode will have an empty
section with a special name: .note.GNU-split-stack

If -r is used to link an object with the split-stack note with an object
without the split-stack note we should issue an error.
Patch implements this, as currently lld output is silently broken.

Detailed info about splitstacks can be found here:
