Linker --wrap option resolves to __wrap_symbol for undefined symbol.
During the compilation of host libportable.a, __HOST__ is defined
to rename all portable functions to __wrap_symbol, and the
real function to __real_symbol. This way libportable.a can be
validated at host w/o changes of user's source code.

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.
