>Description:
	arch/i386/conf/Makefile.i386 specifies -O6 in the compile flags.
	However, for the i386, the maximum level supported by gcc is 2,
	so -O6 makes no sense (it is treated the same as -O2).
>How-To-Repeat:
	Read the code.
>Fix:
	Change to -O2. Or leave this for future expansion, but I'm not
	sure if there'll be 4 more optimization levels for the i386 in
	gcc anytime in the near future.
