It appears to be attempting to link against _neon version of things that it didn't build. Reproducible: Always Steps to Reproduce: 1. emerge firefox using the default/linux/arm64/13.0/desktop profile 2. wait for the build to fail 3. read the build log Actual Results: Build fails. Expected Results: firefox-50 build completes, but like earlier versions, segfaults on launch.
