To be able to build with CONFIG_COMPAT_VDSO=y on arm64 an arm32 toolchain is needed by the kernel build system. This patch implements the necessary logic to locate the arm32 toolchain in an arm64 multilib environment. Signed-off-by: Richard Weinberger <richard@nod.at> --- Hi! This is the least ugly version I came up so far, please tell me what you think. Thanks, //richard P.s: I tested this only on Kirkstone, yet. --- meta/classes-recipe/kernel.bbclass | 33 ++++++++++++++++++++++++++++++ 1 file changed, 33 insertions(+)
