I have some scripts which operate on packages to generate their
(build)dependency tree for Fedora Modularity stuff. It relies on normal binary
and source RPMs for dependency information. However, with dynamic
BuildRequires, I need a way to rebuild sourcerpms with some macros defined. And
I found out that there is no way to get src.rpm with dynamic buildrequires
without installing them.
So I had to do something like
```diff
diff --git a/build/build.c b/build/build.c
index dec7d9608..c1f28b8f5 100644
--- a/build/build.c
+++ b/build/build.c

}
```
and use `rpmbuild -rr -D "_module_build 1" --nodeps /path/to/srpm` and it does
what I need.
So what I want is to say "I am expert, I know src.rpm will have all dynamic
dependencies, just give me src.rpm and not buildreqs.nosrc.rpm.".
