Changes since 20200618-1

• Fixes to buildinfo.json (#25, #27)
• Fixes to cross-compilation linker configurations (#26, #28)
• Fixes to driver flags when selecting linker (#26). This should ensure the toolchain linker is selected, even on hosts with a system linker that supports RISC-V.

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
