[RFA] Fix gold's understanding of ARM v4T/v5T interworking

Subject: [RFA] Fix gold's understanding of ARM v4T/v5T interworking

Hi,

Whilst preparing a patch for gold to work around an issue on ARM1176 CPUs (forthcoming) I noticed that gold doesn't correctly identify between v4T and v5T. In particular:

* It assumes BLX is available on v4T - it is not, BLX is only available from v5T. * It therefore assumes that using the availability of BLX is a good test for whether --fix-v4bx-interworking is also available.

The attached patch fixes these two issues by splitting the
Target_arm::may_use_blx() function into two:
  * Target_arm::may_use_v4t_interworking()
  * Target_arm::may_use_v5t_interworking()

The tests which previous checked may_use_blx() are then directed to use
one of the appropriate may_use_v#t_interworking queries.

I also ported some of the ld-arm/farcall* tests to gold in order to test these fixes.

Tested on arm-none-eabi.

Can someone please review?

Thanks,

Matt
