/// Test the Arm state R_ARM_CALL and R_ARM_JUMP24 relocation to Arm state destinations.
/// R_ARM_CALL is used for branch and link (BL)
/// R_ARM_JUMP24 is used for unconditional and conditional branches (B and B<cc>)
/// Relocations defined in https://github.com/ARM-software/abi-aa/blob/main/aaelf32/aaelf32.rst
