[PATCH v2] ARM: Remove '-p' from LDFLAGS

From: Nathan Chancellor
Date: Mon Dec 31 2018 - 13:12:29 EST


This option is not supported by lld:

ld.lld: error: unknown argument: -p

This has been a no-op in binutils since 2004 (see commit dea514f51da1 in
that tree). Given that the lowest officially supported of binutils for
the kernel is 2.20, which was released in 2009, nobody needs this flag
around so just remove it. Commit 1a381d4a0a9a ("arm64: remove no-op -p
linker flag") did the same for arm64.

v1 -> v2:

* Collect tags

* Remove an additional occurence of '-p' in the bootp Makefile, thank
you to Stefan for pointing it out

* Drop patch 2/2, it will be fixed properly in lld: https://reviews.llvm.org/D55505
