You'll want to put that macro in a file in /usr/lib/rpm/macros.d. Name
the file macros.fpc-srpm to follow the convention, and package it in a
separate package named fpc-srpm-macros. Then ask the maintainers of
redhat-rpm-config to require fpc-srpm-macros.
The macro must be either in redhat-rpm-config or in a package that
redhat-rpm-config requires so that it's always present, because
ExclusiveArch is evaluated before BuildRequires takes effect. A
separate package has the advantage that the same people who maintain
the Free Pascal Compiler can also maintain the macro.
The package should have absolutely minimal dependencies to avoid
bloating a minimal installation, and minimal build-time dependencies to
avoid complicating bootstrapping on new architectures.
As far as I know no special permission is required to do this. The
Packaging Committee discussed taking control of these macros some time
ago, but no decision has been made that I have seen.
