Mark some arm-linux specific xfails marking bug entries

TestCallUserAnonTypedef.py and TestIRInterpreter.py fail to limitation of JIT expressions in handling hard float ABI targets.
TestBSDArchives.py fails due to python unicode error.
TestBuiltinTrap.py fails due to wrong line information generated by some gcc versions.
