O GNU make tem uma opção para fazer um dry-run:
‘-n’
‘--just-print’
‘--dry-run’
‘--recon’
“No-op”. Causes make to print the recipes that are needed to make the targets up to date, but not actually execute them. Note that some recipes are still executed, even with this flag (see How the MAKE Variable Works). Also any recipes needed to update included makefiles are still executed.
Portanto, para a sua situação, basta executar make -n install
para ver os comandos que o make
executaria.
