I don't see these 4 FAILs here.

These two FAIL is because Blackfin as does not accept "SYMBOL = VALUE". 
Blackfin has an algebra assembly syntax. Assigning value to a register 
has the form:

"REG = VALUE"

If there is typo of REG, this will become "SYMBOL = VALUE". That error 
is not easy to notice. So I think it's better to let Blackfin gas reject 
"SYMBOL = VALUE" to detect such error. .set can be used if user want to 
set value to a symbol.

How about the attached patch?
