Checking work/.work.log will tell you what the wrappers are doing,
and in this case it seems that -lterminfo is being dropped. Looking
into why, we're getting this in BUILDLINK_TRANSFORM:

   rm:-lterminfo rm:-ltermlib rm:-ltinfo l:termcap:termcap l:tinfo:terminfo l:curses:terminfo l:ncurses:terminfo rm:-liconv

and tracking down where that's coming from reveals that the problem is
that gettext-tools's bl3.mk includes mk/termcap.buildlink3.mk, and
this comes before alpine's inclusion of terminfo.buildlink3.mk, and
that is injecting unwanted stuff.

Reordering the inclusions makes it work. I'll commit that.

This is not what we want; however, problems like this have come up
before and it isn't clear there's a good solution.

(And sooner or later we'll get one where the link fails one way with
the includes in one order and a different way in the other order, but
we aren't there yet.)
