[U-Boot] ARM : Removing unwind dummy functions

[Gabriel Huau]

Hi,

I would like to know if it's really necessary to keep the dummy
functions in arch/arm/lib/eabi_compat.c.

These function should not be happen in our case (that why the body is
empty).

They have been introduced due to problems with some toolchains that was
referencing these functions. But we can avoid this hack by adding the
option '-fno-unwind-tables' at the compilation time no ? (correct me if
I'm wrong).

Best regards,
