Damien George 9ffb1ad2f8 unix/Makefile: Use -Og instead of -O0 for debug builds. 
For the coverage build this reduces the binary size to about 1/4 of its
size, and seems to help gcov/lcov coverage analysis so that it doesn't miss
lines.

# _FORTIFY_SOURCE is a feature in gcc/glibc which is intended to provide extra
# security for detecting buffer overflows. Some distros (Ubuntu at the very least)
# have it enabled by default.
#
# gcc already optimizes some printf calls to call puts and/or putchar. When
# _FORTIFY_SOURCE is enabled and compiling with -O1 or greater, then some
# printf calls will also be optimized to call __printf_chk (in glibc). Any
# printfs which get redirected to __printf_chk are then no longer synchronized
# with printfs that go through mp_printf.
#
# In MicroPython, we don't want to use the runtime library's printf but rather
# go through mp_printf, so that stdout is properly tied into streams, etc.
# This means that we either need to turn off _FORTIFY_SOURCE or provide our
# own implementation of __printf_chk. We've chosen to turn off _FORTIFY_SOURCE.
# It should also be noted that the use of printf in MicroPython is typically
# quite limited anyways (primarily for debug and some error reporting, etc
# in the unix version).
#
# Information about _FORTIFY_SOURCE seems to be rather scarce. The best I could
# find was this: https://securityblog.redhat.com/2014/03/26/fortify-and-you/
# Original patchset was introduced by
