Seems weird, also no need to run it as root...
Here's my output for comparison :

```
% ./profile-explorer.sh
[+] EROOT : /
[+] PORTDIR : /var/db/repos/gentoo
[+] CURPROFILE: default/linux/amd64/17.0
[+] EAPI : 5

[+] packages (@system)
/var/db/repos/gentoo/profiles/base/packages
/var/db/repos/gentoo/profiles/default/linux/packages
```

And the `explored-packages` file should symply contain a copy of the different inherited packages
files.

To check impact on negating icu on your system : `USE="-icu" emerge -puDU --with-bdeps=y world`

And concerning processor/arch flags I’d suggest keep exploring profiles, take a look at
make.defaults files.
Here the different files you can find according to PMS
