Aargh. I know what PIE does, and I know what PIC does, and I'm still 
asking: Why would we want to use -fpie in the default compiler flags, 
given that said flags can be easily overriden on any system that 
supports -fpie?

In other words, if some security-enhanced Linux distro wants to use 
-fpie all over the place, well and good. Nobody's stopping them.
