Ifort changes compiler version format

The old ifort compiler changes the format version from 2 digits for year to 4 digits:

That makes for strange looking tests, e.g.:
```
if (19, 0, 0) <= ifort.get_version() < (20, 0, 0):
...
if (19, 0, 0) <= ifort.get_version() < (2022, 0, 0):

```

Should we care? We could adjust the version numbers in Fab to be consistent, but:
1. should we bother (ifort is unsupported)
2. do we create more confusion than we solve?

I am happy to just close this and accept the odd looking tests in Fab build scripts.

Start with the Fab build scripts and the ifort.get_version() checks shown in the issue, then compare how the listed compiler output formats are parsed and tested. Done means the handling and tests consistently represent the supported ifort versions, or the issue is closed with the existing behavior explicitly retained.
