Public bug reported:
This works with CodeSourcery's "arm-none-eabi-gcc2 but not with ubuntu's
arm-linux-gnueabi-gcc. If I remove "-lm" it builds with Ubuntu's gcc.
$ make
arm-linux-gnueabi-gcc -c -g -O -Wa,-adhlns=main.lst -std=gnu99 -mthumb
-mcpu=cortex-m3 main.c -o main.o
arm-linux-gnueabi-gcc -g -O -Wa,-adhlns=main.o -std=gnu99 -mthumb
-mcpu=cortex-m3 main.o --output main.elf -Wl,-Map=main.map,--cref -lm -T
link -nostdlib
