We are investigating on errors.Most of the failures are due to
difference in actual and expected strings(Expected strings suits 32-bit
systems and not 64-bit systems)

For ex:-  in statfs test
==============================
Actual: statfs: ustat (42, 0x0000000012345678) = -22 (EINVAL)
statfs: statfs ("abc", 0x0000000012345678) = -2 (ENOENT)
statfs: fstatfs (77, 0x0000000012345678) = -9 (EBADF)
statfs: exit_group (0) =
  statfs: exit (0) =
--------- EXPECTED and NOT MATCHED ----------
statfs: ustat \(42, 0x12345678\) =
statfs: statfs \("abc", 0x12345678\) =
statfs: fstatfs \(77, 0x12345678\) =
========================================

Discussed in detail in bug#4444.

readwrite is failing because of difference expected and actual file
descriptor displayed by readv and wirtev.
==================================================
readwrite: writev (unknown fd, 0x00000000ff97f794, 3) = 15
readwrite: lseek (4, 0, SEEK_SET) = 0
readwrite: lseek (4, 1, SEEK_CUR) = 1
readwrite: lseek (4, -1, SEEK_END) = 75
readwrite: close (4) = 0
readwrite: open ("foobar1", O_RDONLY) = 4
readwrite: read (4, 0x00000000ff97f7c4, 11) = 11
readwrite: read (4, 0x00000000ff97f7c4, 50) = 50
readwrite: readv (unknown fd, 0x00000000ff97f7ac, 3) = 15
readwrite: close (4) = 0
readwrite: exit_group (0) =
  readwrite: exit (0) =
--------- EXPECTED and NOT MATCHED ----------
readwrite: writev \(4, [x0-9a-fA-F]+, 3\) = 15
readwrite: lseek \(4, 0, SEEK_SET\) = 0
readwrite: lseek \(4, 1, SEEK_CUR\) = 1
readwrite: lseek \(4, -1, SEEK_END\) = 75
readwrite: open \("foobar1", O_RDONLY\) = 4
readwrite: read \(4, [x0-9a-fA-F]+, 11\) = 11
readwrite: read \(4, [x0-9a-fA-F]+, 50\) = 50
readwrite: readv \(4, [x0-9a-fA-F]+, 3\) = 15
