PcdValueInit shares the same Edk2\BaseTools\Source\C\PcdValueCommon.c.
To avoid the conflict, it should copy this file to its output directory,
If so, PcdValueCommon.c file will be private for PcdValueInit

copy source file PcdValueCommon.c in the generated Makefile instead
of do it in python script
