unknown "-b" option for rpm !!!

[haneo]

i have used previous verison of redhat (=<7.3) to build rpm i use the -b option (like postfix source to add ath and TLS)

but with redhat 8.0 it say that unknown option -b, but with man rpm i can read theat there is the option -b.
what to do to build my rpms ?
