libosip2: arc: Undefine __arc__ when building for ARC processors
libosip2 appears to have support for the "ARC standard" (Advanced RISC Computing), which is unrelated to Synopsys DesignWare ARC processors. The check for this involves verifying the existence of the "__arc__" macro. Unfortunately, this macro is also present as a predefined built-in for the ARC processors, resulting into build failures.
