Subject: [PATCH 5.10 16/57] ARM: 9025/1: Kconfig: CPU_BIG_ENDIAN depends on !LD_IS_LLD

From: Nick Desaulniers <ndesaulniers@...gle.com>

commit 28187dc8ebd938d574edfc6d9e0f9c51c21ff3f4 upstream.

LLD does not yet support any big endian architectures. Make this config
non-selectable when using LLD until LLD is fixed.
