Details:

Functions dbfread/dbfwrite of the io package fail on big-endian system (in
Debian: s390x, powerpc, ppc64). The following code works fine on little-endian
systems:


f = tempname ();
c = cell (2,1);
c {1, 1} = "a";
c {2, 1} = 1;
dbfwrite (f, c);
x = dbfread (f);


but fails on a 390x system, with the following error message:


error: fdesc(11): out of bound 0
error: called from
    dbfread at line 212 column 25


The bytes in the file are not written/read in the right order on big-endian
machines.
