Vagrant Cascadian reported that mx6cuboxi target no longer builds reproducibility on Debian.
One example of builds mismatches:
00096680: 696e 6700 736f 756e 642d 6461 6900 6465 ing.sound-dai.de -00096690: 7465 6374 2d67 7069 6f73 0000 tect-gpios.. +00096690: 7465 6374 2d67 7069 6f73 0061 tect-gpios.a
The mkimage tool is incorrectly introducing variable bytes after "detect-gpios\0".
Fix the introduction of these variable bytes by using calloc(1, ...) instead of malloc(...).
