Apply 091bb549f7722723b284f63ac665e2aedcf9dec9 to 4.19

Hi Greg and Sasha,

Please apply commit 091bb549f772 ("ARM: 8819/1: Remove '-p' from LDFLAGS") to 4.19 (and earlier if so desired). LLD 14 will remove the '-p' flag [1] for reasons outlined in both the Linux and LLD commit, which will cause our builds to break [2]. I have verified that it applies cleanly back to 4.4, although we only build ARM kernels with LLD on 4.19 and newer, so it is not strictly necessary there.

Cheers, Nathan
