Why should we spend time and space to provide something that doesn't
do anything useful?[1] Nothing prevents the users who want static
linking from building their own libraries. My guess is that those who
do need these kinds of small gains are compiling the relevant libraries
and programs from scratch anyway, using the carefully tuned compiler
options that they've measured as performing the best on their particular
hardware.
