    [gdb/testsuite] Fix gdb.base/examine-address-class.exp for big endian
   =20
    On ppc64-linux and s390x-linux, with test-case
    gdb.base/examine-address-class.exp I get:
    ...
    (gdb) x/1dh (int *) &var^M
    0x3fffffffe560: 0^M
    (gdb) FAIL: $exp: x/1dh (int *) &var
    ...
   =20
    This is caused by big vs. little endian.
   =20
    On x86_64-linux (little endian), we have:
    ...
    (gdb) p /x ((short *)&var)[0]
    $6 =3D 0x2a
    (gdb) p /x ((short *)&var)[1]
    $7 =3D 0x0
    (gdb)
    ...
   =20
    And on ppc64-linux (big endian), we have:
    ...
    (gdb) p /x ((short *)&var)[0]
    $2 =3D 0x0
    (gdb) p /x ((short *)&var)[1]
    $3 =3D 0x2a
    ...
   =20
    Fix this by assigning 0x002a002a to var, making sure that
    ((short *)&var)[0] =3D=3D ((short *)&var)[1] =3D=3D 42.
   =20
    Tested on x86_64-linux, ppc64-linux and s390x-linux.
