EmbeddedPkg/libfdt: Add strncmp macro to use AsciiStrnCmp
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. Check below three commits for the corresponding changes on OpenSBI, https://github.com/riscv/opensbi/commit/8e47649eff96c303e02fbd58cdc6c4ed341066ec https://github.com/riscv/opensbi/commit/2845d2d2cf4fb74a89452ba223995aa4a118c07e https://github.com/riscv/opensbi/commit/2cfd2fc9048806353298a1b967abf985901e36e8 Signed-off-by: Abner Chang <abner.chang@hpe.com> Cc: Leif Lindholm <leif@nuviainc.com> Cc: Ard Biesheuvel <ard.biesheuvel@arm.com> Cc: Daniel Schaefer <daniel.schaefer@hpe.com> Message-Id: <20200806023421.25161-1-abner.chang@hpe.com> Reviewed-by: Leif Lindholm <leif@nuviainc.com> [lersek@redhat.com: remove stray newline between S-o-b and first Cc]
