Yup. However, you're better off doing

In /path/to/your/rpmrc
	include: /usr/lib/rpm/rpmrc
	macros: /usr/lib/rpm/macros:...whatever_you_want...:/path/to/your/macros

and invoking rpmbuild as
	rpmbuild --rcfile /path/to/your/rpmrc ...

which won't read anything but /path/to/your/rpmrc for configuration.

Easier? I'd love to make rpm configuration easier, it's WAY too complicated.

Yeah, but just choose the rpm default (which is portable), or choose
the redhat-rpm-config with a PreReq: on the package, there's little
need to chase both.
