    pch: xfail g++.dg/pch/line-map-3.C
    
    On riscv64-elf and riscv32-elf, the location_t values assigned to
    macro definitions in the command line and on line 1 end up past the
    end of the PCH include line after the PCH is loaded and the main file
    is reentered, so the existing xfails in the testcase, to cover
    messages that refer to line 2, fail to cover line 3, that the messages
    refer on riscv.
    
    This is already improved in the trunk, but the backports are probably
    too invasive, so this patch only adds xfails for line 3 as well.
    
    for  gcc/testsuite/ChangeLog
    
            * g++.dg/pch/line-map-3.C: Xfail messages on line 3 too.
