symlinks

I am confused by the following commit:

commit fc20c26b2500acb6690f03d610d406bffb8944a9

    build: fix symlink selection
    
    The configure test whether to enable the play/rec links is broken,
    and the makefile uses the same condition for both play/rec and soxi.
    Fix both problems.

     enable_playrec_symlinks=yes

How is using alsa/oss/sndio/whatever
related to creating symlinks (or not)?

Why do we have both SYMLINKS and PLAYRECLINKS?
Why is this different for play/rec vs soxi (also below)?

Naively, I would assume we want to create symlinks
for each of play, rec, soxi, or none of them.
