[ELF] Add support for older Arm Architectures with smaller branch range
The Thumb BL and BLX instructions on older Arm Architectures such as v5 and
v6 have a constrained encoding J1 and J2 must equal 1, later Architectures
relaxed this restriction allowing J1 and J2 to be used to calculate a larger
immediate.
This patch adds support for the old encoding, it is used when the build
attributes for the input objects only contain older architectures.
