I believe you are running out of RAM. it's using a _lot_ of it in one
stage. You can check dmesg which will say '(out of swap (killed))' or
osmething like that.
I've added a 2GB swap file to mine to get somewhere.
Unfortunately, even with that issue resolved, I'm unable to build any
pkgsrc GCC, with a similar death for ARM, POWERPC and MIPS - it's dying
on an undefined reference to soft float things in the generated
compiler. I don't know how netbsd GCC differs.

I'll give it another try.
