+ gcc: don't clobber stamp-bits with a symlink to itself
+
+ 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.
