configure: improve last fix
Let's avoid the "if a=$(cmd ...)" since:
- unless being a shell expert, it's not obvious it's testing the exit code
of cmd.
- it's quite fragile, if you pipe cmd into a cmd2 you'll lose the
exit code of cmd.
Instead, we test the emptiness of the variable content afterwards
