    build: Fix CFLAGS and LDFLAGS for the gcov target
    
    A copy and paste thinko duplicated the CFLAGS into the LDFLAGS, so we
    need to fix that. The CFLAGS should also specify the optimization level
    to 0 and turn on debugging notes, in case --enable-debug and
    --enable-maintainer-flags are turned off.
