Linking error occurs when using hipcc compiling file

[mu910125]

hipamd branch: rocm-5.2.x
working directory: /workspace/
hipamd build command:

cmake -DCMAKE_BUILD_TYPE=Debug -DCMAKE_EXPORT_COMPILE_COMMANDS=ON /workspace/src//hipamd -B /workspace/build/Debug//hipamd -DHIP_COMMON_DIR=/workspace/src//HIP '-DCMAKE_PREFIX_PATH=/workspace/build/Debug//comgr;/workspace/build/Debug//llvm-project' -Dhsa-runtime64_DIR=/workspace/install/Debug/rocm/lib/cmake/hsa-runtime64 -DAMD_OPENCL_PATH=/workspace/src//ROCm-OpenCL-Runtime -DROCCLR_PATH=/workspace/src//ROCclr -DCMAKE_INSTALL_PREFIX=/workspace/install/Debug/rocm -DROCM_PATH=/workspace/install/Debug/rocm`

That building command executed outside the building_stage dir is leading to this issuse happen.↓↓

cmake --build /workspace/build/Debug//hipamd --target install

After hipcc building is completed, test hipcc function.

hipcc test file: main.c

#include "hip/hip_runtime.h"
int main()
{
	printf("[HIP]  %d\n", HIP_VERSION);
	return 0;
}

hipcc compile command:hipcc main.c
error output during compile test file:
/usr/bin/ld: /workspace/install/Debug/rocm/lib/libamdhip64.so: undefined reference to __hip_pch'
/usr/bin/ld: /workspace/install/Debug/rocm/lib/libamdhip64.so: undefined reference to __hip_pch_size

I found that the hip_pch.o would not be generated in correct CMAKE_BINARY_DIR when building hipcc executable.
The follow patch can fix this problem.
