find-requires doesn't seem to run during build

[Chris Burel]

I'm running rpmbuild to try to make an rpm for my own glibc.  But for
some reason I'm not getting the expected results from the automatic
dependency finder.   I'm using RPM version 4.4.2.3.  I already looked
at and applied the patch described in this post:
http://lists.rpm.org/pipermail/rpm-maint/2008-April/002031.html

This is clearly wrong, glibc obivously depends on more than bash and
perl.  I can invoke the find-requires script directly on the files
described in the generated rpm, and get more expected results:

I do have a /etc/rpmrc file, but I can't imagine it's doing anything wonky:
