Gacutil will not ngen assemblies ever. A tool called ngen.exe or similar
will do this.

Gacutil will not ever do this, ngen does this

Again, different tool.

RPMs should never ship with ngen'd binaries as they are OS, arch, and
runtime specific, that's just a asking for disaster :P
So, basically what you are saying, is you want whatever code that goes to
implement the GAC respect the fakeroot that you use to build the RPM? If so
I wouldn't worry to much, as something like that will surely exist for
making RPMs of mono itself.
Now, I still wouldn't endorse the use of it, it could have potential issues
down the road if the GAC format changes.
As well, you need to evaluate what the GAC is for, its not a place to store
ALL your assemblies, just a place to store versioned shared assemblies.
