From: Cyril Chemparathy <cchemparathy at 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. :-)
