There is an unfortunate bug in the signoff suppression logic. The first
pass is performed with 'git log', and all signoffs are added to the
supression set, such that the second time (when processing the real
patches) we always suppress the signoffs.

Correct this by only suppressing signoffs in the second pass.

Add missing aes.c placeholder which includes lib/aes.c . Without this
one, tools/env/ will fail to build.

This sort of failure is rare, but the code to deal with it is wrong.
Fix it.

Add an option to specify the output directory to override the
default path '../'. This is useful for building in a ramdisk.

We should avoid the description in Makefile like this

ifdef CONFIG_FIT_SIGNATURE
hostprogs-y += fit_info$(SFX) fit_check_sign$(SFX)
endif

Otherwise, fit_info and fit_check_sign would never be cleaned
by "make clean".
