In addition compilers upto 7.2 did not support anything else than coff
abi. So i don't see any valid reason to add --abi=eabi. Even more you
usually set your silicon for improved optimizer results with e.g
set_target_properties(myTarget PROPERTIES COMPILE_FLAGS "-mv6740")
and i see no reason not to add --abi=eabi there if one needs it.
