@ To support thumb code it is currently necessary to have the _call_via_rX
@ functions exposed to the linker for any program or shared library. PLT
@ references are inadequate - the PLT zaps ip and therefore breaks _call_via_ip
@ (and the compiler does generate this). It is simpler to put all the
@ required code in here - it only amounts to 60 bytes overhead.
@NOTE: it would be better to have the compiler generate this stuff as
@ required...
