[dpdk-dev] [PATCH] mk: add support for gdb debug info generation

[Cyril Chemparathy <cchemparathy@tilera.com>]

It is often useful to build with debug enabled, we add a config
(CONFIG_RTE_TOOLCHAIN_DEBUG) to do so.

Note: This patch does not include corresponding changes for ICC.  The author
pleads abject ignorance in this regard, and welcomes recommendations. :-)
