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.

The portable (ARM) jmp_buf and sigjmp_buf structures are smaller than the native
(MIPS) structures so it is not safe to simply call the standard bionic routines.
Luckily there is a lot of redundant space in the standard MIPS structures
and it is possible to save all of the needed registers in the area provided by the
ARM application.
