I am just guessing but I will bet your makefile is now very 
incorrect.  Why don't you post that file if it is a reasonable 
length.

Mine looks like this (but Yahoo will trash it):

NAME = Playstation Controller

CC = arm-elf-gcc
LD = arm-elf-ld -v
AR = arm-elf-ar
AS = arm-elf-as
CP = arm-elf-objcopy
OD = arm-elf-objdump

ARCHIVE1= "C:/Program Files/GNUARM/lib/gcc/arm-elf/3.4.3"
ARCHIVE2= "C:/Program Files/GNUARM/arm-elf/lib"
LIBFLAGS= -L${ARCHIVE2} -lc -lg -lm -L$(ARCHIVE1) -lgcc 
CFLAGS  = -I./ -c -fno-common -O0 -g -Wa,-ahls=$*.lst -Wall
AFLAGS  = -ahls -mapcs-32 -o crt.o
LFLAGS  =  -Map main.map -Tmain.cmd
CPFLAGS = -O ihex
ODFLAGS = -x --syms

objects = main.o conio.o spi.o timer.o interrupt.o setup.o

all: test

clean:
  -rm *.o *.lst *.dmp *.hex *.map *.out
	
test: main.out
 @ echo "...copying"
 $(CP) $(CPFLAGS) main.out main.hex
 $(OD) $(ODFLAGS) main.out > main.dmp

main.out: main.cmd crt.o $(objects)
 @ echo "..linking"
 $(LD) $(LFLAGS) -o main.out crt.o $(objects) $(LIBFLAGS)

crt.o: crt.s
 @ echo ".assembling"
 $(AS) $(AFLAGS) crt.s > crt.lst

$(objects): %.o: %.c
 @ echo ".compiling " $<
 $(CC) -c $(CFLAGS) $< -o $@

main.o: main.c setup.h spi.h conio.h timer.h lpc210x.h
conio.o: conio.c conio.h lpc210x.h
setup.o: setup.c setup.h spi.h lpc210x.h
spi.o: spi.c spi.h lpc210x.h
timer.o: timer.c timer.h
interrupt.o: interrupt.c interrupt.h lpc210x.h

The important part is the ARCHIVE1 and ARCHIVE2 paths and the 
LIBFLAGS definition.  The linker won't scan back and forth (without 
help) so the libraries have to be specified in the proper order.

Don't try to copy this file directly.  Make wants certain fields 
separated by TABS and they are now SPACES.
