[dpdk-dev] [PATCH v4] Clang compile error with RTE_LIBRTE_MEMPOOL_DEBUG enabled.

[Keith Wiles <keith.wiles@windriver.com>]

When enabling RTE_LIBRTE_MEMPOOL_DEBUG and compiling with clang
compiler an error occurs, because ifdefed code now includes GCC pragmas.

GCC 4.4 is when push_options and pop_options pragma show up.

Rework to include Thomas’s suggestion to drop push/pop pragma directives for
ignore/error directives.
