Comment # 4 on bug 1133258 from heming zhao

Hello Martin,

Can you upload your spec file in attachment?
I can't reproduce this error in my environment:

spec file (lvm2.spec)
```
# Please submit bugfixes or comments via https://bugs.opensuse.org/
#

+ %global optflags %optflags %{_lto_cflags} <==== only add this line in the
head of this file, is it right?

%define _unpackaged_files_terminate_build 0
%define _udevdir %(pkg-config --variable=udevdir udev)
%define applib liblvm2app2_2
%define cmdlib liblvm2cmd2_02
```

My env:
```
