The -static overrides the -pie and binaries aren't position independent anymore. Use -static-pie instead which would produce a static and position independent binary. This has been caught by clang's warnings: clang: warning: argument unused during compilation: '-pie' [-Wunused-command-line-argument] Tested with both gcc and clang after this change.
