Add support for the relocation type R_ARM_ARM_THM_CALL which is
produced for the ARM Thumb BL and BLX (branch immediate)
instructions.
These instructions are used for non-static functions like
void test1(void)
{
}
void main(void)
{
test1();
}
Without support for this relocation, test1() has to be static.
