I'm basing this on the web page http://wiki.rtems.org/wiki/index.php/Building_Tool_RPM_Packages as well as notes I kept when I last did this last April.  This is to build a multilib with SPE support, I haven't gotten that far yet, I'm just trying to reproduce what's shipped.

It's the last part of the sentence.

(With my Fedora hat on) F12 was discontinued by upstream Fedora => F12 
does not receive any updates anymore and means exposing yourself to 
significant security risks. You should upgrade to a more recent Fedora 
(F13 or F14).

(With my RTEMS hat on) As a consequence of this, support for F12 was 
removed from the RTEMS rpm.specs. This means, the conditionals inside of 
the spec, when building for F12 now expand to different settings than 
they used to, driving the build-process into an untested (and probably 
dysfunctional) path.

That said, there are several possibilities you could apply:
a) Upgrade to a more recent Fedora.
b) Build your modified rpm.spec in a CentOS5 mock environment.
The result would be a CentOS5 package, you could use on F12.
c) You to restore F12 support in your rpm spec (Diff the most recent 
*.spec against your older *.spec and re-add the lines referring to 
"%{?fc12}"; Alternatively: Walk through the specs history in RTEMS CVS)

I strongly recommend choosing a) - It's the only clean solution of these 
alternatives.
