That's correct. All ARM GCC compilers can generate code for all 
ARM variants (the hf compiler can generate softfloat code and the 
softfloat compiler can generate hf code as well). The difference 
between the compilers are the shipped libraries. You probably 
can't use the shipped libgcc etc from these compilers for thumb 
targets.
