| Subject: arm64: Default to building compat vDSO with clang when |
| CONFIG_CC_IS_CLANG |
| |
| From: Will Deacon <will@kernel.org> |
| |
| [ Upstream commit 24ee01a927bfe56c66429ec4b1df6955a814adc8 ] |
| |
| 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. |
