- update mkelfImageto version 1.16

- cleanup the w83627hf header, and function names
- rename power_led to w83627hf_power_led
- rename w832627hf_power_after_power_fail to w83627hf_power_after_power_fail
- smbus_read_block != smbus_read_byte
- Update build_opt_tble to handle checksum entries

+%description
+mkelfImage is a program that makes a elf boot image for linux kernel images.
+The image should work with any i386 multiboot compliant boot loader, an ELF boot
+loader that passes no options, a loader compliant with the linuxBIOS elf booting
+spec or with the linux kexec kernel patch.  A key feature here is that nothing 
+relies upon BIOS calls, but they are made when necessary.  This is useful for 
+systems running linuxbios.
