   5     gcc: don't clobber stamp-bits with a symlink to itself
   6
   7     Several versions of gcc have an issue in libstdc++v3 where the build may
   8     clobber stamp-bits with a link to itself.  This doesn't manifest itself
   9     on all systems.  On several Ubuntu systems, this doesn't appear to be a
  10     problem, but it is an issue on Fedora 16 systems.
  11
  12     To fix the issue, we'll simply filter out stamp-bits from the symlinks
  13     to be generated.
  14
  15     Note: gcc 4.4.7 is unaffected by this issue, so no fix is necessary
  16     there.
