Stable Version 2.0.0

New features:

Upgraded to LLVM 12.0.0
GCC now builds for llvmtools and final system
Eliminated /opt/gnu and /llvmtools/gnu. GCC will now be installed in /llvmtools and /usr
Elfutils can be patched to build under LLVM
Added script to switch between GCC or LLVM as system compiler system
Added script to switch between GNU's binutils or LLVM's binary tools
Zlib or Zlib-ng can be built
Ninja or Samurai can be built.
Build initramfs image without the mkinitramfs script

Skarnet's utmps segfaults if built with clang
Diskboot.img of grub is not correctly built with clang. Grub requires GCC and patching.
Perl 5.34.0 fails to cross-compile for llvmtools. Use perl 5.32.1 for llvmtools and perl 5.34.0 for final system
Perl will not build with system installed zlib-ng. Use perl's bundled zlib source as a workaround.
