[dpdk-dev] Compiling DPDK is not working on Red Hat 6.7

[Christian Ehrhardt]

Hi,
checking "man clock_gettime" I see: "Link with -lrt (only for glibc
versions before 2.17)."

RH 6.7 is at glibc 2.12, I haven't check the build, but you might easily
run the make with V=1 and see the call.
Check if it contains -lrt for the linking step.
