Hi Cyril,
We already do have 'EXTRA_CFLAGS' and 'EXTRA_LDFLAGS' that you can use to enable debug, or any other compiler/linker options you need.
Wonder, why that is not enough?
Thanks
Konstantin

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. :-)
