GCC 8 PowerPC Argument Changes

[Joel Sherrill]

 Hi

I am using GCC 8 to test my bsp_specs changes. On the
powerpc -mno-spe is gone.

I don't know of a case where we have a BSP that checks
if GCC supports an argument or not. I think we have just
changed the custom file when we upgraded GCC.

Any thoughts on the correct argument or better approach
than just to change the custom file when we bump GCC?

Thanks.
