For SUSE we install the debuginfo in places like:
for e.g. the libusb 1.0 shared library.
Other distros might do it differently.

It is standard macro hidden in our RPM build process. It happens after the
regular package "make install" is done.
It extracts the debuginfo fully automatic, no packager attention required.
Basically it does objcopy of the debug sections for all libraries and binaries,
and afterwards it does "strip --strip-unneeded"
The package build itself is not supposed to strip binaries.
