commit 910299c49f55e7954f1c5a4350faf0bd2cc6ae1c
Author: Yoshinori Sato <ysato(a)users.sourceforge.jp>
Date: Sat Jan 9 16:27:58 2016 +0900
h8300: O_DIRECT and O_DIRECTORY swapping.
Different define of latest kernel.
kernel define is
#define O_DIRECT 00040000 /* direct disk access hint */
#define O_DIRECTORY 00200000 /* must be a directory */

commit e4c5a6c49bbbc735ea867f59bef681a27fc3641e
Author: Eugene Rudoy <gene(a)freetz.org>
Date: Sat Jan 9 12:00:43 2016 +0100
ARCH_NATIVE_BIT should in the first place be passed when building utils for host
ARCH_NATIVE_BIT should in the first place be passed when building utils
for host (BUILD_CFLAGS-utils). It could also be passed when building utils
for target (CFLAGS-utils), but this is actually not necessary
as ARCH_NATIVE_BIT and __WORDSIZE are identical in this case.
Fixes 5ec4477584b69fe5f1410649b2eb3a63835fb649 (makes it actually work).
