Projects that rely on a linker script usually specify a memory location
where the executable should be placed. This directly contradicts the
default option -fpie for position independent executables. In fact, using
PIE generates a GOT, which might be undesirable for developers that need
control over the generated sections.
Would it be positive to assume -fno-pie on these situations?

I'm not sure if it is valid to assume that a linker script "usually" specifies a fixed memory location.
