dpdk: support build with external & multilib toolchainssumo

This fixes dpdk build when using an external toolchain by adding
the HOST_CC_ARCH & TOOLCHAIN_OPTIONS to EXTRA_CFLAGS the way
standard Yocto does it to gather all the necessary flags for
compilation.
The TOOLCHAIN_OPTIONS variable also provides the sysroot flag, so
no need to explicitly provide the sysroot.

This commit also fixes the build when using a multilib toolchain
by adding the LDEMULATION flags to the LDFLAGS via TUNE_LDARGS
which are required while linking with a multilib toolchain.
