linphone: arc: Undefine __arc__ when building for ARC processors

This patch is similar to 821a6d63. Libexosip2 defines symbol __arc__, which
gets in contradiction with same symbol defined by the GCC for the Synopsys
DesignWare ARC cores. Previous patch undefined __arc__ for libosip2 and
libexosip2, however linphone includes headers from libexosip2, which causes
build failure unless same patch is applied to it.
