@knc1: What's the issue with CT-NG when building a GCC 4.7/Glibc 2.6/2.5 TC?
The only issue I have when doing this with glibc 2.9 (not the same, okay, but if it can help
) is the need to backport (well, not really, just apply it, actually) the make-3.82 compat patch for glibc (and the fact that it hits a very
weird bug that breaks the build when using older GNU make versions when building a softfp TC).
