This relands https://chromium.googlesource.com/breakpad/breakpad/src/+/e3035bc406cee8a4d765e59ad46eb828705f17f4, which was accidentally committed to breakpad/breakpad/src, the read-only mirror of src in breakpad/breakpad. (Well, it should have been read-only.) See https://crbug.com/766164. This fixes issues with glibc-2.26. See https://bugs.gentoo.org/show_bug.cgi?id=628782 , https://sourceware.org/git/?p=glibc.git;h=251287734e89a52da3db682a8241eb6bccc050c9 , and https://sourceware.org/ml/libc-alpha/2017-08/msg00010.html for context.
