Enable compat vDSO support in the arm64 defconfig. Note that the default compiler is set to arm-linux-gnueabihf-. For this to take effect and for the compat vDSO to compile correctly, it is required that this compiler is in the PATH.
I do not have such a compiler in my path by default. I hope that we handle that gracefully, rather than causing a build failure. Can't we detect the presence of the compat compiler at config time, as happens for the native compiler? Thanks, Mark.
