[PATCH] Makeconf: controlling the optimization level

[Neal H Walfield]

This patch adds a variable, COPTIMIZE, to Makeconf.  This allows the
user to easily control the level of optimization for a single file
or a single module.  For example:

        # cd libdiskfs
        # COPTIMIZE= make

would build libdiskfs with minimal optimizations thus not eliminating
variables that may aid in debugging.  This is necessary as gcc selects
the highest flags thus:

        # CFLAGS=-O make

would be overridden by the default value in CFLAGS.

        * Makeconf (COPTIMIZE): New variable.  Define this to -O3 if
        COPTIMIZE it not already defined.
        (CFLAGS): Do not use -O3 directly, rather, use $(COPTIMIZE).
