Discard GNU attributes at link time as kernel doesn't use it at all. Solves a dozen of the following ld warnings (one per every file):

Misc: sort DISCARDS section entries alphabetically.
Hmm, I wonder what is causing the appearance of .eh_frame? With help I tracked down all the causes of this on x86, arm, and arm64, so that's why it's not in the asm-generic DISCARDS section. I suspect this could be cleaned up for mips too?
Similarly for .gnu.attributes. What is generating that? (Or, more specifically, why is it both being generated AND discarded?)
