Hi Miguel,

This definitely helped- I was using the master branch earlier. Can I
make a PR to add this to the documentation on rust/quick-start page?

I did run into some other errors while building though:

```
error: unknown argument: '-mindirect-branch=thunk-extern', err: true
error: unknown argument: '-mindirect-branch-register', err: true
error: unsupported option '-mrecord-mcount' for target
'x86_64-pc-linux-gnu', err: true
thread 'main' panicked at 'Unable to generate bindings: ()'
```
The full logs are here: https://paste.ubuntu.com/p/xqd4pMBdrb/

Since a few places online suggested the error might be related to gcc
and clang, I tried compiling with clang versions 9.0 /10.0 /11.0 and
gcc versions 8 /9 / 10 but the error persists. I am not sure how to
proceed here :/

Thanks,
Sumera
