+Subject: [PATCH] Fix build of shared library on architectures needing -fPIC
+
+Certain architectures, like Sparc and Sparc64 require objects to be
+built with -fPIC (and not just -fpic) to be usable in shared
+libraries. On other architectures, -fPIC is the same as -fpic so this
+patch doesn't affect such architectures.
