Project not buildable in Sierra / Xcode 8?

Hey Chris!

I tried to build OpusKit using the latest iOS stable release SDK (10.1) and unfortunately I get errors when running the build script.

Using opus-1.1.3.tar.gz

configure: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details

config.log says that instead of gcc the system uses clang and it cannot recognize some commands:

clang: error: argument to '-V' is missing (expected 1 value)
clang: error: no input files
configure:3534: $? = 1
configure:3523: gcc -qversion >&5
clang: error: unknown argument: '-qversion'

Any ideas?

Update: If I remove i386 and x86_64 from the ARCHS string (line 50 of the build script), it builds successfully.

Finally! I was able to get it to build by adding "--host=x86_64" on line 107.

Should I make a PR about it?
