[swift-dev] Android: wrong ld (linker) keeps being invoked

[Brian Gesiak]

Eric,

This is definitely something I'd like to improve. I believe karwa's new
`-tools-directory` option (https://github.com/apple/swift/pull/2912 and
https://github.com/apple/swift/pull/4543) could take care of this problem.
If so, we should update docs/Android.md to recommend using that. Could you
try using that?

As for me, I've found success with the symlink solution up until now. I'm
not sure why it doesn't work in your case...

I believe that in later versions of Clang, -fuse-ld accepts full paths to
linkers. So it may work if you have a sufficiently recent version --
although I haven't tried myself.
