ARM expanse some functions to others. For example, _Unwind_GetIP will be inlined to _Unwind_GetGR, which will be inlined to _Unwind_VRS_Get. This happens at header-included level. However, we use Itanium _Unwind_* header as portable one. We do the inlining in ARM libportable to prevent undefined reference to these functions.
