Backtrace dump is available: - always on Windows - on Linux/BSD if execinfo.h is available (not anymore on Alpine)
The flag RTE_BACKTRACE was set unconditionnaly in rte_config.h. It is now set only if the feature is available. Note: Alpine Linux has decided to remove libexecinfo support, so this change will allow to compile DPDK on recent Alpine Linux.
