My suspect at this point is that the string passed to CONFIG_CROSS_COMPILE_COMPAT_VDSO is not completely empty. In fact if I do CONFIG_CROSS_COMPILE_COMPAT_VDSO=" " (single space), I do have a failure similar to the one you reported. > _______________________________________________ > linux-arm-kernel mailing list > linux-arm-kernel@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel > -- Regards, Vincenzo
