Description of problem:
When building an RPM package, if a file is installed to RPM_BUILD_ROOT
and hardlinked to another file name and an %{attr} statement added to
the first one, rpm does a double chown/chmod and resets permissions on
the first one.

for instance (in the %install section)...

touch RPM_BUILD_ROOT/sbin/a
chmod 644 RPM_BUILD_ROOT/sbin/a
ln RPM_BUILD_ROOT/sbin/a RPM_BUILD_ROOT/sbin/b

in the %files section...

%attr(0755,root,root) /sbin/a
/sbin/b


when installed both files with be 0644.

this is not really a bug in rpm, but maybe a warning would be a good idea?


Version-Release number of selected component (if applicable):
rpm-4.3.3 & rpm-4.4

How reproducible:
Always

Steps to Reproduce:
1.create an rpm specfile which hardlinks one file to another name
2.create an attr statement  for first file and leave second file
without an %attr() statement
3.install rpm
    

Actual Results:  both files are set with default permissions of second
file above

Expected Results:  maybe a warning message?

There are a vanishingly small number of packages attempting both hardlinks
and %attr, so the work detecting different %attr modifiers on hardlinks is not
worth the effort imho.

The command
     rpm -V pkg
will detect multiple %attr apllied to hardlinks.
