If the sstate files are installed into a sysroot from the sstate cache,
the directory to the main sysroot can change and the symlinks aren't
adjusted to account for this. This is a problem specific to the toolchain
bootstrap process. This patch adds up a function to recreate the
symlinks, hence ensuring they always point at the correct location.
