The problem happens because the default value of CFLAGS in the
Makefile is "-g", which causes GCC to emit debug info.  Setting CFLAGS
to -O2 doesn't strip the debug info, but GCC will not produce the
debug info because there's no -g in CFLAGS.  "make CFLAGS=-O2"
overrides the value of CFLAGS in the Makefile, not adds to whatever
the Makefile says.
