File build_csparse_shared.patch of Package suitesparse.30992

From: toddrme2178@gmail.com
Date: 2018-03-07
Subject: Build shared CSparse

Upstream does not support installing CSparse as a shared library.
We need it is a shared library.  This patch modifies the
makefil to make sure it is installed correctly.
