meta-toolchain: Permit outgoing symlinks

The generated installation script includes this snippet:

    # change all symlinks pointing to /usr/local/oe-sdk-hardcoded-buildpath
    for l in $($SUDO_EXEC find $native_sysroot -type l); do
        $SUDO_EXEC ln -sfn $(readlink $l|$SUDO_EXEC sed -e "s:$SDK_BUILD_PATH:$target_sdk_dir:") $l
        if [ $? -ne 0 ]; then
            echo "Failed to setup symlinks. Relocate script failed. Abort!"
            exit 1
        fi
    done

This redirects the outgoing links at installation time, so it is
incorrect to error for those symlinks as removing them actually modifies
the installation away from its intention.
