+  # Nasty hack to get around being unable to reliably add configuration to gcc,
+  # hence the gcc specs are modified, combined with Baserock's rootfs protection
+  # preventing specs being modified before builds.
+  # The limitation is overcome by installing files as part of a chunk, which
+  # overwrites previous files.
+  # New specs were added for the bootstrap builds, but after stage2 we start
+  # having chrooted builds, so the old specs need to be replaced.
+  # Unfortunately we can't just replace the specs with the ones gcc produces,
+  # since gcc behaves differently without specs to with specs it produces!
+  # So we use a **NASTY HACK** to replace the specs symlink with one that
+  # points to a file that doesn't exist.
