解决u-boot 2016.11 ”ERROR: Makefile:1385: recipe for target 'checkarmreloc' failed”

在编译u-boot-2016.05时出现如下问题：

解决办法：
搜索 “u-boot contains unexpected relocations”，没有搜索到任何内容，那么我们再尝试搜索checkarmreloc：

lvxiaoliang@lvxiaoliang-virtual-machine:~/Ftp/tmp/u-boot-2016.05$ grep "checkarmreloc" * -nR

arch/arm/config.mk:111:ALL-y += checkarmreloc

Makefile:1384:checkarmreloc: u-boot

在顶层Makefile中有如下语句:

#########################################################################

# ARM relocations should all be R_ARM_RELATIVE (32-bit) or
# R_AARCH64_RELATIVE (64-bit).
checkarmreloc: u-boot
        @RELOC="`$(CROSS_COMPILE)readelf -r -W $< | cut -d ' ' -f 4 | \
                grep R_A | sort -u`"; \
        if test "$$RELOC" != "R_ARM_RELATIVE" -a \
                 "$$RELOC" != "R_AARCH64_RELATIVE"; then \
                echo "$< contains unexpected relocations: $$RELOC"; \
                false; \
        fi

env: scripts_basic
        $(Q)$(MAKE) $(build)=tools/$@

tools-only: scripts_basic $(version_h) $(timestamp_h)
        $(Q)$(MAKE) $(build)=tools

tools-all: export HOST_TOOLS_ALL=y
tools-all: env tools ;

cross_tools: export CROSS_BUILD_TOOLS=y
cross_tools: tools ;

#########################################################################                                             

那么我们就别编译checkarmreloc了，所以我们注释掉arch/arm/config.mk的第111行：

#ALL-y += checkarmreloc

然后就能编译通过了
