See libgcc/Makefile.in:

ifeq ($(CUSTOM_CRTSTUFF),)
# Compile two additional files that are linked with every program
# linked using GCC on systems using COFF or ELF, for the sake of C++
# constructors.
crtbegin$(objext): $(srcdir)/crtstuff.c
$(crt_compile) $(CRTSTUFF_T_CFLAGS) -c $< -DCRT_BEGIN

crtend$(objext): $(srcdir)/crtstuff.c
$(crt_compile) $(CRTSTUFF_T_CFLAGS) -c $< -DCRT_END


And so on.  libgcc/crtstuff.c is compiled multiple times to yield
different object files.
