arm64: vmlinux.lds: account for spurious empty .igot.plt sections
Now that we started making the linker warn about orphan sections (input sections that are not explicitly consumed by an output section), some configurations produce the following warning: aarch64-linux-gnu-ld: warning: orphan section `.igot.plt' from `arch/arm64/kernel/head.o' being placed in section `.igot.plt' It could be any file that triggers this - head.o is simply the first input file in the link - and the resulting .igot.plt section never actually appears in vmlinux as it turns out to be empty. So let's add .igot.plt to our collection of input sections to disregard unless they are empty.
