Increase BUILD_MIN_BIOSTABLE for large roms
BUILD_MIN_BIOSTABLE reserves space in the f-segment. Some data structures -- for example disk drives known to seabios -- must be stored there, so the space available here limits the number of devices seabios is able to manage. This patch sets BUILD_MIN_BIOSTABLE to 8k for bios images being 256k or larger in size. 32bit code is moved off in that case, so we have more room in the f-segment then.
