[PATCH v2 17/18] arm64: disable RANDOMIZE_MODULE_REGION_FULL with LTO_CLANG

From: Sami Tolvanen
Date: Wed Nov 15 2017 - 16:37:02 EST


RANDOMIZE_MODULE_REGION_FULL results in "overflow in relocation type 275"
when loading a module linked with GNU gold. As a workaround, disable when
LTO_CLANG is selected.
