I'm trying to build 1.6_STABLE with specific -march=XXX flags,
	but without them being set in the distrib images (which overflows
	the image size).

	I can almost do it with

	.if !defined(DBG) || ${DBG} != "-Os"
	[set stuff]
	.endif

	but that breaks in distrib/i386/floppies/ramdisk-rescuesmall:
	- The Makefile sets BOOTMODEL, IMAGE, and IMAGESIZE
	- Then includes ../common/Makefile.ramdisk
	- That then includes '<bsd.own.mk>', then _later_ sets DBG=-Os

	I could make the conditional  .if !defined(IMAGESIZE) but
	it seems like there should be a cleaner way to do this...
