qcom SDM450 android11平台新建device的编译报错

最近在移植SDM450 Android 11的项目，新建device的过程中发现一个编译报错，模块为高通GPS相关的slim_daemon，默认的target为msm8953_64编译ok. 新建的device编译就是失败，错误log如下：

初步怀疑点是device目录下及vendor/qcom/proprietary下的msm8953相关的配置，是否都考虑到了. 反复确认，没找到下手的变量的差异可以排除，最终通过比较out目录下对应的编译

out\target\product\oemdevice\obj\STATIC_LIBRARIES\libslimutils_intermediates\src\qmislim_target.d

发现问题所在，发现编译报错使用的工具链为

prebuilts/clang/host/linux-x86/clang-r383902b1/bin/clang++ -pie -nostdlib -Bdynamic -Wl,-dynamic-linker,/system/bin/linker64 -Wl,--gc-sections -Wl,

msm8953_64编译正常编译的工具链为： 

vendor/qcom/proprietary/llvm-arm-toolchain-ship/10.0/lib/clang/10.0.7/include/stddef.h \

然后简单追踪了下调用流程：
