Historically rpm only generated automatic dependencies on files with 
executable bits, and for a long time the executable bit was the only way 
of controlling dependency generation on per-file level.

Over time various exceptions to the rule have gotten added, and in rpm 
 >= 4.9.x this is simply a matter of generator configuration: note the 
"exeonly" flag in /usr/lib/rpm/fileattrs/elf.attr

Technically it could fairly easily be changed now that >= 4.9.x has 
other means of filtering dependencies on per-file level, but the 
traditional behavior was preserved in the name of compatibility, people 
tend to expect similar behavior across different rpm versions.
