SAMD: delay.h: No such file or directory

[red-scorp]

Following happens when build for M0 or Zero boards both in Arduino SDK and platform-io.

C:\Users\***\Documents\Arduino\libraries\U8glib\src\clib\u8g_delay.c:57:14: fatal error: delay.h: No such file or directory
#    include <delay.h>
              ^~~~~~~~~
compilation terminated.

It helps to comment the include out:

/* issue 353 */
//#if defined(ARDUINO_ARCH_SAMD)
//#    include <delay.h>
//#endif

Could you fix it yourself or should I go a full circle with cloning and issuing pull request?
