Reduces hot-cache link time from 49s to 23s (gcc) and binary size from 72M to
67M (gcc) -- faster links and a 5MB smaller binary.
(With clang, it's 36s to 19.5s and 75M to 69M.)
It also makes the chrome/android/arm64 config more similar to most other build
configs.
We used to not use this because of
https://sourceware.org/bugzilla/show_bug.cgi?id=18348 , but the gold binary
in NDK r12b (which we currently use) has the flags added in the patches on
that bug, so it should be fine now.
