Fix cut detection in configure.ac

[lealem47]

Description

Some versions of cut are missing the --version and --help options, so the cut detection command was failing even if the tool is available. This change checks the availability of the tool by testing the command with an empty string.

Testing

Tested on macOS by forcing the usage of cut over colrm with the patch below. The configure command will fail but will succeed with this PR.
