My dmesg is full of segfaults in as/ld, and compiling many packages has become an exercise in futility. Originally on binutils 2.21-r1 and then tried unmasking and using 2.22, but both give the same issue. At first I thought what you're probably thinking right now: bad hardware. It's a brand new system, so I don't believe overheating is a concern (and there is nothing in mcelog), and reboots soon after a failure have the bios saying the CPU is ~50c (lm-sensors gives what I believe are bogus readings (~25c)). I have run memtest and the system has passed. And the funny thing is, some things I can compile over and over and over and over and will never receive any segfaults (like the linux kernel). Other packages, will fail 99% of the time. This tells me it's not a hardware problem. Of course, I'm happy to be wrong.

=sys-devel/binutils-2.21.1-r1 [ebuild R ] sys-devel/binutils-2.21.1-r1 USE="zlib -multislot -multitarget -nls* -static-libs -test -vanilla" ================================================ I'm happy to include the build log, but it's massive, and I'm not sure you'd get anything from it. Just a random *** error in the middle of the make, and then portage behaving as you'd expect once that happens. And I don't think my build environment has any bearing on the binaries in binutils at all since this is a brand new install, and the current binutils in place came out of the stage3 binary, not a compilation of my own.
Your success with the Linux kernel might be telling. Can you try building some stuff without -march=native?
Sorry for the delay; was running more tests. I left the computer doing a memtest overnight. It passed with no errors. I recompiled binutils without -march=native, no change. Lots of segfaults in as. I tried doing a quickpkg on my laptop (amd64, i3), and copying the package over and installing it on the atom. I brought over both glibc and binutils. The system behaves the same. And just to appease myself, I recompiled the kernel another dozen times. No issues.
I meant build *other* packages without -march=native. My hypothesis is that -march=native is triggering the segfaults.
Turns out I'm a horrible, filthy liar. I was out of ideas, so the system was doing a: while true ; do make clean; make bzImage ; done It just crashed on perhaps the 20th build. While it seems to happen less on a kernel build, it appears it does happen on a kernel build. I'm starting to suspect a bad CPU. I'm going to do an RMA on this one and get another to see if the issue comes back. Feel free to mark the bug invalid in the meantime.
Alright. As always, feel free to reopen if/when you isolate the problem a bit.
I'd suggest to check the RAM first. We have some atom's and all of them had problems with a lot of RAM sticks. Make sure you use ones that are tested by the vendor. So to clarify: The RAM may be ok, it's the atom/BIOS itself. Also try a BIOS upgrade.
