It's good to know that...

Indeed binaries compiled for 32 bits processors are compatible for 64 bits
processor, but you don't get the same performance as if they were compilled
for a 64 bits architecture.

These changes only applies to compilation optimizations, so it should
improve  performance. If everything still working, I'll add this flag to
build environment.
