Autobuild3 Documentation Updated for Core 4.0+

The "AOSC Cadet Training" - a handbook for new AOSC OS packagers - has been updated by Mingcong Bai with information about new configuration options, changes, and syntactic sugar (and of course, those deprecated with the update), here below is a quick re-cap of what's changed:

• autobuild/defines has received some new configuration options:
  • AB_FLAGS_O3 for switching between -O2 and -O3 optimization level;
  • AB_FLAGS_SPECS for toggling the use of compiler/linker hardening specs on/off;
  • LTO is now enabled by default on amd64/x86_64;
• autobuild/pax specifies post-installation operations to mark executables/libraries/directories for PaX/Grsecurity compatibility;
• Autobuild3 now processes architecture-aware patches contained in autobuild/patches/ with architectural suffixes;
• The old perl_local Autobuild3 filter is now renamed as perl, which additionally purges all .packlist files in the packaging root;
