[dpdk-dev] mk: use extra cflags when linking apps with the compiler
Checks
Commit Message
From: John Jacques <john.jacques@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.
