[ARC] Enable init_array support.
gcc's common configure script has a subtle flaw that it only tests
{init,fini.preinit}_array support when NOT cross compiling. This causes
cross builds to erroneously deduce that the feature is not supported by
the target.

|configure:22941: checking for .preinit_array/.init_array/.fini_array support
|configure:23106: checking cross compile... guessing
|configure:23111: result: no
The right fix is to enable this for *all* cross setups (and address any
fallouts). However in the short-term to enable ARC glibc port to upstream,
force enable this for ARC.
This has been discussed at length on glibc mailing list [1], [2]
