Vincenzo Frascino 0df2c90eba arm64: vdso32: Detect binutils support for dmb ishld ... Older versions of binutils (prior to 2.24) do not support the "ISHLD" option for memory barrier instructions, which leads to a build failure when assembling the vdso32 library. Add a compilation time mechanism that detects if binutils supports those instructions and configure the kernel accordingly.
