It seems that you are using Linux on your RPi3 and when I compile any
project on my Linux desktop box I get the following compiler message:
"Note: DWARF debug information cannot be used with smart linking on this
target, switching to static linking"
So even after stripping the debug symbols the size is significantly
larger because of the deactivated smart linking.

As far as I remember this happens with all of the possible debug formats
I can choose from. So to allow smart linking you probably have to
disable the generation of debug symbols completely. (Though I have never
used the RPi3 target, so I can only guess from using x86 Linux.)

By the way if you are using Lazarus, the compiler note is hidden by
default: Right click in the message window -> "Filter Hints without
Source Position"
