Add '-lm' to your linker options to get the user supplied (thanks
Michael Stumpf!) libraries.  The standard libraries don't have the
routines you want  and are big, fat and slow (but portable code!).

>From my makefile...
 LDFLAGS = -Wl,-lm,-Map=$(<:.o=.gcc),--cref,-v -mmcu=$(GCCMCU)
%elf: %o
 $(CC) $< $(GCCLIB) $(LDFLAGS) -o $@
