Building Marvell

I have a handful of NAS boxes (NSA310, DS207+) lying around and it
occurred to me to see if I can have NetBSD. After much reading, I
decided I'd need to build a kernel. I have a Banana Pi that could use
the workout.

NetBSD banana 10.0 NetBSD 10.0 (XTLBPI) #0: Thu Aug  8 ... evbarm

It could build a kernel for itself with make and boot that fine.

But building the MARVELL_NAS config, make depend stops at:

#    create  MARVELL_NAS/cpufunc_asm_arm10.d

*** Error code 1

So, I'm wondering if this is user error or has the config become
non-functional for current compiler or something.

This is "gcc (nb3 20231008) 10.5.0" and should be pretty regular 10
install if there is such a thing for evbarm. Generic ISO and uboot
rather than the prebuilt image, as that didn't seem to fit on a 4 G
card.
