Subject: [PATCH] ARC: fix allnoconfig builds

In case of allnoconfig HAVE_MOD_ARCH_SPECIFIC=no
because ARC_DW2_UNWIND=no as well.

This enables default "struct mod_arch_specific" from
./include/asm-generic/module.h which clashes with ARC's one.

Before e514943bbfe1 ("ARC: module: Fix !CONFIG_ARC_DW2_UNWIND builds")
ARC's "struct mod_arch_specific" was hidden for !CONFIG_ARC_DW2_UNWIND
builds but not anymore.

So to make our life easier and escape more complicated ifdeffed constructions in
sources let's unconditionally select CONFIG_HAVE_MOD_ARCH_SPECIFIC for ARC.
