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