Yes, indeed. For those checking against embedded sums, there are few
options, but to fix their scripts. But for those that do not use sums
(and might or not check the sigs), providing the symlinks is a life-saver
for all the already-released versions of those tools.

Fact is, even if those projects already have fixes (crosstool-NG has,
buildroot should follow suite when I'm done pushing the change), it might
not be an option for users to upgrade for various reasons, especially
those in corporate environments where versions are written in stone, and an
upgrade requires much more than simply an upstream version string change.

Yes, it does fixes more than it breaks. Those using sums are already and
irremediably broken. Those not using sums would be fixed with the symlinks.
