Looks to be a good idea if it is really automatic.

Unfortunately, it depends on $CC which is not commonly exported.
What about defaulting to gcc?

RTE_CONFIG_TEMPLATE is not defined in this patch (and I do not see the benefit in next patch).

Thomas, 
     Does this mean that this patch is not going into this release? It has been acked for almost a month now, with no further comment. The one hour between your comment and the release of RC4 did not give me a reasonable amount of time to address your concerns. I also feel that the lack of comments in the last month should mean that the patch should be applied as is. If changes are required, I am happy to address in the next release. 
Regards,
Dave.
