• a/glibc-solibs-2.29-arm-4.txz
• d/binutils-2.32-arm-3.txz
• d/libtool-2.4.6-arm-10.txz
  Recompiled to update embedded GCC version number.
• d/llvm-8.0.0-arm-2.txz
  Recompiled with -DLLVM_INSTALL_UTILS=ON. Thanks to Lockywolf.
  llvm had always been built with gcc, but now fails with gcc-9.
  We're now building with clang. Ideally this will be reverted to build with
  gcc again (or at least the build script will be fixed to make it optional, as I
  quite like knowing that it can be re-boot strapped if necessary).
  If anybody wants to fix it, please send patches this way.

  Added some additional tools. Thanks to Markus Wiesner.

• kernels/*

• d/gcc-gdc-9.1.0-arm-1.txz
  This package contains the newly added D language support.
• d/gcc-go-9.1.0-arm-1.txz
  Shared library .so-version bump.
  Moved back in to the main tree from /testing. The simple test case I have now
  passes, so let's see how this plays out now that the package gets exercised.
