Thanks.  I think there should however be testcases covering the 
BFD_RELOC_C6000_ABS_L16 case - at present all the tests seem to use mvk 
and mvkh, so only covering the other two cases.

The code and tests in this patch version are OK as far as they go, but in 
addition to the tests needed mentioned above I think there should also be 
a linker test covering nonzero results of the H16 relocation (maybe cases 
where the result is negative).
