How does one profile an 8 color device?
Depends on how the device is being driven. If it's being driven by a
QuickDraw (or GDI) driver, then profile it RGB.
If it's being driven by a RIP, then you need to ask the RIP manufacturer
about how their RIP prepares the files. There aren't that many that will
accept an eight channel separation. Most accept a four channel separation
and during RIP they generate (as a part of the screening process)
additional channels. So in this case you make a CMYK profile.

How does one even make a file for that?
If the RIP actually supports more than four channel data and retain
integrity (that is, if you ask it to print 100% orange, that it actually
uses ONLY orange ink and doesn't reseparate internally and use other ink
colors in addition to orange ink) then you do this in one of two ways:
1.) RIP supports an 8-channel ICC profile. So you print RGB data to the
RIP and it uses the ICC profile to separate the data into 8-channels and
sends it onto the printer. That's the easiest way.
2.) Need to find software or a Photoshop plug-in that will use an
8-channel ICC profile to product an 8-channel separation, then save the
resulting 8-channel file as DCS 2.0; place in a QuarkXPress file and
print.
IOW, it all depends on your RIP.
