Build with cflag `GC_FINAL_STATS` failed

Build with master (02f80c6)

I'm trying to build julia with option GC_FINAL_STATS.

julia/src/options.h

Lines 67 to 70 in eeb0b69

	// profiling options
	// GC_FINAL_STATS prints total GC stats at exit
	// #define GC_FINAL_STATS

Make.user

# valgrind
CFLAGS = -DMEMDEBUG -DMEMDEBUG2 -DGC_FINAL_STATS
