gdb-entryval-crash-*.patch files
    
    The three patches:
    
      gdb-entryval-crash-1of3.patch
      gdb-entryval-crash-2of3.patch
      gdb-entryval-crash-3of3.patch
    
    are not being applied to the Fedora build of GDB, since this commit to
    the Fedora GDB repository:
    
      commit 902c8e5abca19590075fa0f8457f5d7cec9303ca
      Date:   Thu Jul 24 20:04:47 2014 +0200
    
          Rebase to FSF GDB 7.7.91.20140724 (pre-7.8 snapshot).
    
    The contents of the first two were reverting an upstream commit,
    which, based on the dialog in the patch files, was done to mask a bug
    in a different part of GDB, which I assume is now fixed.
    
    The third patch adds a couple of tests, which are now all upstream,
    and passing, I assume these tests covered the issue that was causing
    the problem with the first two patches.
    
    Given these patches are not being applied, and the relevant work seems
    to be in upstream GDB, I propose we drop these three files from the
    repository.
