The rpm-build subpackage will need "Requires: gdb >= V-R".  Obviously, the
patch can't go in anywhere until that gdb is built in dist-rawhide.

It's certainly Fedora-specific and only for Fedora 14.

I don't quite understand what file this writes to.
Is it implicitly "<symfile name>.index" in the argument directory?

IMHO, the file name should have "gdb" in the name.  
This is really not any very generic sort of index for the information.

What's this for?  It just repeats the work of making and recording the
build-id symlink to the .debug file.  Unless you're being quite subtle
somehow I've missed, this doesn't do anything with the index file.
Do you mean something like:

	make_id_link "$id" "/usr/lib/debug$dn/$bn" .index

?  That gets you a /usr/lib/debug/.build-id/xx/yyy.index symlink
to ../../usr/bin/foobar.index for example.
