Comment # 1 on bug 1212909 from Daniel Garcia

I've detected that this happens when the project configuration in obs has

<debuginfo><disabled/></debuginfo>

In that case the rpmbuild command is run with "--undefine
_enable_debug_packages" and looks like this is the cause of non fully stripped
binaries.

When the debuginfo is enabled the script /usr/lib/rpm/find-debuginfo is run and
for each .so file it runs objcopy with the --strip-all flag.

The brp-15-strip-debug [1] script is run even if the debuginfo is disabled, but
looks like this script doesn't strip all the symbols so just with this, rpmlint
find the 'no stripped' string in the file magic.
