  To: dev; +Cc: Bruce Richardson, Tyler Retzlaff

Stop writing RTE_TOOLCHAIN_XXX macros to rte_build_config.h. When an
application builds it doesn't necessarily use the same toolchain that
DPDK was built with.

Instead evaluate toolchain predefined macros and define
RTE_TOOLCHAIN_XXX macros as appropriate each time rte_config.h is
preprocessed.
