I've found this http://fedoraproject.org/wiki/Releases/FeatureBuildId
and now I understand where this is all about.

But in my case is't simple: fpc doesn't support the .note.gnu.build-id
section for now. It's not an official section, so that's not that
strange. Support for it can be added, offcourse. But not in the current
release i'm packaging.

Maybe I could add a parameter to fpc so that it uses the --build-id
parameter when calling ld. I'll try that solution.

But as a consequence all fpc-programs in Fedora should add that
parameter to their build-scripts. I don't really like that solution...

Btw: the problem to identify binaries which you want to solve with this
trick, doesn't exist with fpc-binaries. What you're trying to solve is a
real gcc-problem only. So if this can be disabled in some way for
fpc-programs, that would be great.
