        src/sys/arch/x68k/stand/boot_ufs: Makefile boot.S

Log Message:
Change primary bootloader's load address from 0x0f0000 to 0x003000.
- Moving addresses closer eliminates bunch of this linker errors:
    in function `entry0':
    relocation truncated to fit: R_68K_16 against `edata'+ffffffffffff8000
    :
- By this change, harmful -noinhibit-exec option can also be removed.
  Finally, we can break the builds when assemble error occurs!
- Load address of secondary is 0x6000, so that this change limits
  text+data+bss 12KB or less.  Current actual size is 5~7KB.
  I think it should be fine.
- cd9660 can have up to 30KB text+data in its bootarea.  Even in this
  case, this change limits text+data+bss 12KB or less (currently, it's
  about 6KB).  However, I take breaking the builds on errors rather than
  future size limitation.
There is no user visible changes or interface changes.
