I got one I could upgrade to 8 gigs of ram. Makes a big difference.

That doesn't help me reproduce this build failure, though.

I don't do multilib. I'm trying to set up a target environment you can  
build stuff under. If you can natively build a new Linux From Scratch  
chroot, my work is done.

If I _can_ build a 64-bit only environment, I'd like to do that. That's  
how the x86-64 target works, for example. (You can add 32 bit libraries  
after the fact, by building them  natively on target.)

Last I checked uClibc didn't support it, but musl might someday.

I don't know. I'm trying to learn enough to find out. I'll probably  
have to try it and see what breaks.

Clang needs C++ on the host in order to build (but only recently wrote  
its own C++ standard library), didn't have its own binutils last I  
checked... I'll need to engage with this more at some point but it's  
not strongly luring me out of my niche yet.
