Tested on NDK 15b.

I had this issue but I thought I'd tested it and found it no longer occurred. I'll look into it again.

[inclement]

I'm finding this quite perplexing - looking closely at the build logs, there are some small differences between the calls to ar and ranlib when using the different SDKs, but the Makefiles are the same. I'm not even sure if it's these differences exactly that are responsible for the problem.

[germn]

I've tested with 15c and everything worked fine. Problem is related to 15b only.

[inclement]

I was testing with NDK 16 beta 1, where the issue does occur. I'll try with 15c.

[inclement]

It seems to work now, I've tested with 15c and 16.

I'll reopen if others can still reproduce the issue.
