I just wondered whether it adds some overhead that for most cases is
not really necessary when executables are loaded at fixed addresses
without need for relocations to its own symbols at runtime really.

Some systems may require position independent executables but even
GCC I think needs a configure option to make them by default.

Also there is still the ARM-PE target, aka wince.  I don't know if
it's still functional (or ever was) though.
