The output for `--print-enbled-extensions` was implemented using the following
format:
```
Extensions enabled for the given AArch64 target
Architecture Feature(s) Description
FEAT_ETE Enable Embedded
Trace Extension
```
I chose not to include the `+foo` values in the output mostly because not all
of the extensions are exposed via `-march`/`-mcpu` and the implications between
them are not very clear. I'm happy to add these on a extra column, though, if
you think there's value to it.
