+Subject: [PATCH 260/266] Require -fPIC instead of just -fPIE for
+ -reduce-relocations
+
+GCC 5 combined with a recent binutils have a new optimization that
+allows them to generate copy relocations even in -fPIE code. Clang has
+the same functionality when compiling an executable with -flto. We need
+to let the compilers know that they cannot use copy relocations, so they
+need to use really position-independent code.
+
+Position independent code throughout is not really required. We just
+need the compilers to use position-independent access to symbols coming
+from the Qt libraries, but there's currently no other way of doing that.
