Newer gcc complain about missing mode argument when a new file is
created. This is an extract of man-pages:

 "The mode argument specifies the file mode bits be applied when
 a new file is created.  This argument must be supplied when
 O_CREAT or O_TMPFILE is specified in flags"

Does this warning only show up when compiling for the host or also when
compiling barebox itself?

It happens when I compile barebox itself (or something is obviously wrong):
