[RFA/testsuite] Update selftest.exp

[Michael Elizabeth Chastain]

Proofread.  Remember to update the copyright year on the first line.
Other than that, perfect.

Tested on 132 configurations:

  target   = native
  host     = i686-pc-linux-gnu%rh-8
  gdb      = gdb_5_3-branch%20021125, HEAD%20021125
  gcc      = 2.95.3, 3.0.4, 3.1, 3.1.1, 3.2, 3.2-7-rh, 3.2.1, gcc-3_2-branch%20021125, HEAD%20021125
  binutils = 2.13.1, 2.13.90.0.2-rh, binutils-2_13-branch%20021125, HEAD%20021125
  glibc    = 2.2.93-5-rh
  gformat  = dwarf2, stabs+

Fixes the bug in all configurations.  No regressions introduced.

Recommended for approval on mainline.  After commit to mainline, wait
one week, then recommended for approval on 5.3 branch if no problems arise.
Not a showstopper for 5.3 release.
