编译RK3288内核，使用arm-linux-gnueabihf出现的问题。

  OBJCOPY pie/libpie_stage2.o
  LD      pie/pie_stage2.o
arm-linux-gnueabihf-ld: BFD (GNU Binutils for Ubuntu) 2.22 internal error, aborting at ../../bfd/elflink.c line 8758 in elf_link_output_extsym

arm-linux-gnueabihf-ld: Please report this bug.

解决方法是不再使用apt-get install安装的而使用Android源码中的prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-就没有问题了。
