[compiler-rt] r310400 - Add NetBSD support in asan_interceptors.cc

[Diana Picus via llvm-commits]

Hi Kamil,

This bot is segfaulting on some ASAN tests and this commit looks like
the only compiler-rt change in the range:
http://lab.llvm.org:8011/builders/clang-cmake-armv7-a15-full/builds/9452

Any idea what the problem might be?

Thanks,
Diana
