Please review that bug for more context and additional comments, but update this bug.

### Original description

**What steps will reproduce the problem?**
1. "make atmega8_isp" (assuming you've got updated source that has that target)

**What is the expected output? What do you see instead?**
expected output is to build a mega8 version of bootloader and download it to a mega8 chip via whatever programmer is configured. What happens is that the "isp" target always specifies a value for the "extended" fuse byte, which mega8 doesn't have, so avrdude issues an error message and quits.

**Please use labels and text to provide additional information.**

optiboot on atmega8 isn't "supported" specifically, so this may be slow to change. The workaround is to manually (cut & paste) run the equivalent avrdude commands without the EFUSE programming section.
