For the implementation which utilizes libfdt provided in EmbeddedPkg however it uses strncmp function in the libfdt helper library, libfdt_env.h should provide the macro implied with edk2 strncmp implementation. The example is RISC-V OpenSBI library. edk2 RISC-V port uses OpenSBI library and incorporate with edk2 libfdt. edk2 libfdt_env.h provides the necessary macros to build OpenSBI which uses fdt functions in edk2 environment. However, OpenSBI also has libfdt helper library that uses strncmp function which is not defined in edk2 libfdt_env.h. This commit addresses the build issue caused by missing strncmp macro in libfdt_env.h.
