I don't know what the "Command does not fulfill its conditions" error message means exactly. However, a Buildroot-generated compiler is targeted for hosted compilation. I am not sure that it is capable of generating code for a freestanding environment, where the FIQ attribute would be relevant. You may be better off downloading an ARM-supported toolchain from
