The code should be compiled with -O0 for gdb use, otherwise various
optimizations make it very difficult to follow the execution flow.
With this patch adding DEBUG=1 to the environment or make command line
causes the usb_updater utility built with -O0 instead of -O3. The
debug flag is being changed to -g from -g3 as this code is not going
to be able to benefit from the g3 features, especially when built
inside chroot.
BRANCH=none
BUG=none
TEST=verified that gdb can properly control execution when make is
invoked with DEBUG=1
