od: use -fipa-pta

Improves performance of emulators (e.g. gambatte on rs90) at the cost of slightly increased build times. Per GCC documentation: > Perform interprocedural pointer analysis and interprocedural modification and reference analysis. > This option can cause excessive memory and compile-time usage on large compilation units. > It is not enabled by default at any optimization level.
