    'libgomp.c/interop-hsa.c': GCN offloading only
    
    Fix-up for commit 8d84ea28510054fbbb8a2b7441916bd75e29163f
    "OpenMP, GCN: Add interop-hsa testcase", which added 
'libgomp.c/interop-hsa.c'.
    If nvptx offloading compilation is enabled in addition to GCN, the former 
ICEs:

                [...]/gcc/final.cc:4328
    
    Regardless of the issue that nvptx offloading compilation probably shouldn't
    ICE, the 'asm' insert clearly is valid for GCN only.
    
            libgomp/
            * testsuite/libgomp.c/interop-hsa.c: GCN offloading only.
    
    (cherry picked from commit 85ad0d84fcec720c1d94b9bda9a617ced70ba5d2)
