From 24ee01a927bfe56c66429ec4b1df6955a814adc8 Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Fri, 4 Oct 2019 14:08:13 +0100 Subject: [PATCH] arm64: Default to building compat vDSO with clang when CONFIG_CC_IS_CLANG Rather than force the use of GCC for the compat cross-compiler, instead extract the target from CROSS_COMPILE_COMPAT and pass it to clang if the main compiler is clang.
