[erlang-questions] Build Erlang from source failed with GitHub tag OTP-21.2.5

[Bryan Paxton]

 I have run into this issue when I had artifacts left over from previous
builds in my repo. Try to executing the following (after ensuring you
save any changes you might have made) :


git clean -xfd


Then run ./otp_build autoconf again
