This, I suspect is a hangover from an historic foobar that no ones gone 
back to fix.  The original assembler tests used AS and LD making for a 
very raw test framework.  It was an intentional decision, very like the 
simulator tests, rely on an absolute minimum to get things working.

Unfortunatly, sometime back a change switched LD to GCC but at the time 
no one realised (or those reviewing remembered gdb.asm's intent). 
Anyway, it needs to be switched back and that isn't going to be pleasant ...
