0.9.2: make fails with ld: symbol(s) not found for architecture i386 in XCode 10.2.1

[jjarava]

Hi!

When compiling 0.9.2 manually with XCode 10.2.1, make fails with the message: ld: symbol(s) not found for architecture i386

The message ld: warning: The i386 architecture is deprecated for macOS (remove from the Xcode build setting: ARCHS) on the output gave me a hint, and changing the Makefile to remove -arch i386 from the invocation makes it compile successfully.

Below is the full output of make:

$ make
