    ld: Update mixed LTO and non-LTO relocatable output tests
    
    Since mixed LTO and non-LTO relocatable output is only supported on ELF
    platforms, limit these tests to ELF targets.  Since powerpc64 elfv1
    defines a function symbol on its procedure descriptor, which is in a
    data section, rather than on the code for that function, allow both D
    and T for nm test on mixed object.
    
            * testsuite/ld-plugin/lto.exp: Limits  mixed LTO and non-LTO
            relocatable output tests to ELF targets.  Allow both D and T for
            nm test on mixed object.
