Appendix C also contains information concerning the build order. While there might need to be a few tweaks yet, this information is complete enough at this point to close out the long-standing ticket #684. Many thanks to Chris Staub, Dan Nicholson and Manuel Canales Esparcia for helping get this finished. git-svn-id: http://svn.linuxfromscratch.org/LFS/trunk/BOOK@7536 4aa44e1e-78dd-0310-a6d2-fbcd4c07a689
