All depends on how build systems are configured. Get a copy of rpm --showrc
from a RH build, and configure your build machine the same way.

There are as few overrides and "secret sauce" as possible in beehive, by 
intent.
OTOH, arch happens to be one configuration parameter that is overridden 
frequently.

There are certainly no per-package unique build configuration flags by 
intent. OTOH,
configurations can and do rot, and there is the occaisional need to 
expedite a package
build with a hack to get the job done.
