Subject[PATCH 0/3] compat vdso cleanups
From
Three fixes for compat vdso, the first two are related, the third is
standalone.

The first two fix a warning observed for `mrproper` targets when
$(CROSS_COMPILE_COMPAT)gcc is not in the $PATH.

The third makes is so that CROSS_COMPILE_COMPAT is not necessary to
select COMPAT_VDSO when using clang+lld.

Based on arm64/linux.git/for-next/misc.

Nick Desaulniers (3):
arm64: vdso32: drop the test for dmb ishld
arm64: vdso32: lazily invoke COMPAT_CC
arm64: vdso32: require CROSS_COMPILE_COMPAT for gcc+bfd
