LTO and r17

[Andrey Alekseenko]

I've noticed that in r17 (at least beta1) there is an issue that gold
linker emits broken debug info.
On the other side LTO does not work with bfd linker, but only with gold.

So, what can you recommend? Not using LTO with r17, or the issue will be
resolved before r17 release?

We're using debug information to generate breakpad symbols for production
builds and for ndk-stack which is invoked on testing stand if crash occurs.

Last I checked LTO works with bfd.

Oh, thank you!
It really works with bfd & r17-beta1, I'm already used to that it only
works with -fuse-ld=gold.

Yeah, clang used to require gold for LTO. I think bfd gas worked only since
r16.
