Those units contain initialization sections which drag in a lot of code. You might want to try to
strip explicitly unused symbols by compiling with -Xs.

I guess the reason is that you are using the variants unit. On windows, most of the variants stuff
can be handled by the OS. On unix style systems, everything is handled by FPC libraries which
emulate how windows handles variants.
