[rfa/testsuite] gdb1250.exp: make 'break abort' work with new pending breakpoints

[Michael Elizabeth Chastain]

This patch works great for me:

  native i686-pc-linux-gnu
  gcc 2.95.3, 3.3.3, HEAD
  binutils 2.14, HEAD
  dwarf-2, stabs+

It fixes the problem in gdb1250.exp and doesn't break anything else.
