I lowered the GCC requirement to 7, gcc7 seems fine for c++17.

I didn't realize, but upstream gcc contained no support for NetBSD
ARM EABI at all. It was upstreamed in gcc 10, with this patch:

https://github.com/gcc-mirror/gcc/commit/b27c10823418d58d70274ee3a7378e1aca21d418

But gcc10 still fails for other reasons (related to libunwind?)
