    testsuite: AMDGCN test for vect-early-break_38.c as well to consistent 
architecture [PR119286]
    
    I had missed this one during the AMDGCN test failures.
    
    Like vect-early-break_18.c this test is also scalaring the
    loads and thus leading to unexpected vectorization for this
    testcase.

            PR target/119286
            * gcc.dg/vect/vect-early-break_38.c: Force -march=gfx908 for amdgcn.
