为什么提交这份PR (why to submit this PR)

#7583

你的解决方案是什么 (what is your solution)

# include libraries

objs.extend(SConscript(os.path.join(libraries_path_prefix, stm32_library, 'SConscript')))

# include drivers

objs.extend(SConscript(os.path.join(libraries_path_prefix, 'HAL_Drivers', 'SConscript')))

命令使用错误,调整为如下方式即可

# include libraries

objs.extend(SConscript(os.path.join(libraries_path_prefix, stm32_library, 'SConscript'), variant_dir='build/libraries/'+stm32_library, duplicate=0))

# include drivers

objs.extend(SConscript(os.path.join(libraries_path_prefix, 'HAL_Drivers', 'SConscript'),variant_dir='build/libraries/'+'HAL_Drivers', duplicate=0))

修改参考

rt-thread/tools/building.py

Line 391 in d2308d4

objs.extend(SConscript(Rtt_Root + '/src/SConscript', variant_dir=kernel_vdir + '/src', duplicate=0))

在什么测试环境下测试通过 (what is the test environment)

scons 测试通过,

同时搜索此命令(objs.extend(SC)调用位置，发现大量bsp均有错误使用，但是由于工作量较大，当前我仅修改了stm32 作为参考
另外又发现汇编文件的生成仍在在源码路径，推测是 *.s文件不在当前路径下导致
