Makefile apparently runs "strip" without arguments

[ProducerMatt]

Attempting to compile on NixOS. The compilation goes fine until:

(etc.)
gcc -c -DNDEBUG=1 -g  type.c
gcc  hugs.o edit.o observe.o builtin.o char.o compiler.o errors.o evaluator.o ffi.o goal.o input.o machdep.o machine.o module.o opts.o output.o plugin...
strip
Usage: /nix/store/rq6bh3qfrqnyqwik0w3q6w180zg3w2pa-binutils-2.38/bin/strip <option(s)> in-file(s)
 Removes symbols and sections from files
 The options are:
(etc.)

Any idea what's happening?

EDIT: for any Nix users, here's the NUR package
