This script generate new build target in koji for SIGS.

OPTIONS:

   -a           ARCHES             	 : Force arches e.g : "x86_64","aarch64 i686", etc...

   -b			                 : Enable non public bootstrap repo (SCLO SIG only)

   -c		COLLECTION               : Enable collection in the buildroot

                                           e.g : mariadb100

					   A single collection can be used at this time.
