make: Fix parallel building with some container platforms (VPP-880)
With some Linux container platforms /proc/cpuinfo reads as an empty file. (Aside: stat on /proc/cpuinfo always indicates a length of zero bytes, regardless of its content). This has the effect that the make '-j' parameter being passed the unhelpful value of '0' both in build-root/Makefile and dpdk/Makefile. Make complains with the error: make: the '-j' option requires a positive integer argument This patch checks for '0' and replaces it with '2' as a reasonable number of jobs to run in parallel when the CPU count isn't known (and assumed to be one). It also makes the value determination consistent between VPP and DPDK (2*ncpu). Change-Id: I78b89420114a825fab4d339e4f9291d486b7b9c8 Signed-off-by: Chris Luke <chrisy@flirble.org>
