[ARC] Don't convert _DYNAMIC@ to _GLOBAL_OFFSET_TABLE_

Browse Source 
Historically the arc abi demanded that a GOT[0] should be referencible as
[pc+_DYNAMIC@gotpc].  Hence we convert a _DYNAMIC@gotpc to a GOTPC reference to
_GLOBAL_OFFSET_TABLE_.

This is no longer the case and uClibc and upcomming GNU libc don't expect this
to happen.
