Fails to build without config.toml

[diwic]

$ ./x.py build
Traceback (most recent call last):
  File "./x.py", line 20, in <module>
    bootstrap.main()
  File ".../rustc/src/bootstrap/bootstrap.py", line 756, in main
    bootstrap()
  File ".../rustc/src/bootstrap/bootstrap.py", line 683, in bootstrap
    with open(args.config or 'config.toml') as config:
IOError: [Errno 2] No such file or directory: 'config.toml'

cp config.toml.example config.toml fixes the issue, but is this intended to be a required step? According to README.md and CONTRIBUTING.md it seems like you're only supposed to have to do this in case you actually want to change something in the configuration.

Should be fixed once #44754 lands; prioritized.

This seems to be fixed. (#44754 was merged way back in 2017, and I tested it myself with 1.25.0 just now.)
