This is the actual error:

../../../bin/llvm-tblgen: /usr/lib/x86_64-linux-gnu/libstdc++.so.6:
    version GLIBCXX_3.4.26 not found (required by ../../../bin/llvm-tblgen)

I have never tripped over this particular error myself, but I can think oftwo plausible explanations for it:

  1. somewhere in the Rust source tree is an object file compiled by a C++ compiler that doesn't match the one on your computer
  2. your C++ compiler's header files are out of sync with its runtime library (possibly because you installed a newer C++ compiler by hand, instead of updating it through your OS's package manager)

(1) is easier to investigate: I would suggest wiping out and re-downloading the Rust source tree from scratch, and then doing something along the lines of

find /home/first/src/rust/2/rustc-1.47.0-src \
    \( -name '*.o' -o -name '*.a' -o -name '*.la' -o -name '*.so' \) \
    -exec sh -c 'for o; do mv "$o" "$o.not"; done' {} +

and then trying to build again. If that still doesn't work, then you need to consider the possibility of (2). We'd need to know which Linux distribution you're using to help with that.
