The pkg_config helper for premake was not checking for errors. When it failed to run, either when it is not installed or the queried package is not found, a cryptic error message would be printed: "Error: .../xenia/third_party/premake-core/src/base/string.lua:36: attempt to index a nil value (upvalue 's')" Fix this by checking the return status when calling pkg-config and printing a descriptive error message.
