[dpdk-dev] [PATCH] mk: use extra cflags when linking apps with the compiler

From: John Jacques <john.jacques at intel.com>

When using the compiler to link applications, include EXTRA_CFLAGS. This
is needed, for example, when cross-compiling, to pass --sysroot.
GCC cross-compilers built with Yocto don't use the --with-sysroot option,
making it necessary to pass --sysroot command-line option.
