xstereograph.s390x: W: executable-stack /usr/lib64/libsx.so
The binary declares the stack as executable.  Executable stack is usually an
error as it is only needed if the code contains GCC trampolines or similar
constructs which uses code on the stack.  One common source for needlessly
executable stack cases are object files built from assembler files which don't
define a proper .note.GNU-stack section.

xstereograph.s390x: W: install-file-in-docs /usr/share/doc/packages/xstereograph/stereograph/INSTALL
A file whose name suggests that it contains installation instructions is
included in the package.  Such instructions are often not relevant for already
installed packages; if this is the case for this file and it does not contain
any information that is of interest after the package has been built and
installed, do not include the file in the binary package.

xstereograph.s390x: W: shared-lib-calls-exit /usr/lib64/libsx.so exit@GLIBC_2.2
This library package calls exit() or _exit(), probably in a non-fork()
context. Doing so from a library is strongly discouraged - when a library
function calls exit(), it prevents the calling program from handling the
error, reporting it to the user, closing files properly, and cleaning up any
state that the program has. It is preferred for the library to return an
actual error code and let the calling program decide how to handle the
situation.

A file that is needed only e.g. when developing or building software is
included in a non-devel package. These files should go in devel packages.
