Changes

Updates Clang/LLVM with a different implementation of the jump guards hardening (it should be more robust and the transformation no longer affects assembly files). Otherwise, the tool versions are the same as in the previous release.

Changes since 20200606-1

• libstdc++ is now statically linked to Clang/LLVM. We are linking with a version that is more recent than what several distros provide by default (e.g. ubuntu-16.04), so this should fix such dependency issues
• The combined toolchain tarballs should no longer have any broken symlinks
• Binutils and GCC now contain a bug report email address
• Various build clean-ups and sanity checks
