>Description:
	It tries to build simdcoverage and fails.
        This probably not only affects amiga but every cpu type
	that doesn't have simd support

>How-To-Repeat:
	
>Fix:
	The "don't try SIMD for CPU types that don't have that"
        logic did work in 3.1.3, so getting that back would be one option.
	If that is too cumbersome, at least not-for-$arch should be set.
