This is an excellent question! Digging into this details, it stands that
the dar_static_2.6.14 binary had still its symbol table (in other words
binary was stripped).

I have rebuilt it properly and it has an equivalent size as the other ones.

Note that in documentation the recommended last stage of installation is
"make install-strip" not "make install" precisely for that reason:
avoiding such bigger binaries (there is no noticeable difference in
performance).
