Had this been our first PLT implementation I would agree.

Given that all the necessary code for an eager PLT implementation is
fresh on svn, it seems that now is a point where it would be easy to
add it. There is also a move towards doing eager .got evaluation for
security reasons (fedora 23 always uses -z now for example). Once that
is the case, a simpler .plt/.got are nice additions.

Given that there is '-z now', how about '-z eager'?
