But for example if we use: `make CROSS_TOOLCHAIN=riscv64-gcc TARGET_ARCH=riscv64` and do not specify CROSS_BINUTILS_PREFIX in env, embed_mfs.sh cannot find the correct objdump. This patch just replaces using of objdump with elfdump to collect needed information. Later we may also put an ELFDUMP in CROSSENV and use it in embed_mfs.sh .
