Pay attention to the newlib of 64 bits on Linux in x86-64

In x86-64 Linux, when using 64 bits newlib should pay attention to a point, to add "-Disable-multilib" When configure, otherwise there will be the following error, because newlib will upload 32 bits of newlib together with others, will add-M32 when all files are uploaded
