This can be confusing yes. Even more if a makefile asks for LD and you
know you've got ld.exe, but should say gcc.

And that's no problem to either make nor gcc. It can be confusing to
make if you need xyz.o and you both have xyz.c and xyz.asm.

If you have got xyz.c and abc.asm and the makefile:
CC = gcc
CFLAGS = -m486 -s -Wall -Werror
OBJS = xyz.o abc.o
gall.exe: $(OBJS); gcc -o $@ $(OBJS)
%.o: %.asm; nasm $< -o $@ -fcoff $(NASMFLAGS)
will do what you want, and expect it to do.
(because the %.o: %.c rule is builtin.You can make it explicit also,
for clarity and to control the proces completely)

bye now,
 Robert.
