Essentially some more polishing: - image path extracted from downstream build log; - extended error/warning regexp a bit so those with color grep options get even prettier output. Notes: - "1024" a magic number (briefly explained when introduced) moved to a sort of variable; - "100 lines" for tail(1) is a rule-of-thumb taking into account typical amount of hasher/mkimage exhaust given GLOBAL_VERBOSE.
