Well, I've looked in commit history, and found that:

Although, I'm not sure if it is okay for it to be `-pthread`, and not `-

I bet on regression (since I'm using source-based distro and it's pretty 
unlikely to have that mismatch here.

Well, I'll try to check if manual fixing of libpcre's pkg-config file would 
help. Now it really looks like libpcre issue.

By the way,

Here, libpthread is inherited from dynamic libpcre, and (I hope) it doesn't 
interfere with any zsh's internal work. So, I guess, it shouldn't interfere in 
static too.

But I'm not sure if it should be worked around in zsh at all (in case, if I'll 
confirm that is libpcre's pc-file bug).
