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).
