I've even been complaining about b2g still using gcc 4.4 on trunk... This adds too much risk of security patches failing to backport from mozilla-central to ESR 24. Remember that one of the design goals of ESR is to minimize the amount of effort we put into it so that ESR doesn't slow down real Firefox. AFAICT, most people don't even want ESR at all. So, a constraint to keep ESR 24 compatible with GCC needs to include some resources for doing the backports.
How does this add too much risk? Patches that we backport to ESR are usually fairly small, and there is already some risk involved as the codebases diverge, of course.
