Add a »-i 10« option for your first attempt.  By default, the AVR
ships with the internal RC oscillator running at 1 MHz.  That causes
the maximal possible ISP speed to be less than 250 kHz.  If you've got
a sufficiently fast computer these days, chances are good that the
bit-banging will exceed that speed unless it's slowed down.  The -i10
option will cause an additional 10 µs delay between each bit change,
that should be sufficient.

Once you've got it running from the external 12 MHz oscillator, you
can drop that option again (and gain some programming speed).
