+ # 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.
