I see. But at least, if I bootstrap on a certain compiler, then
configure, it will be able to build there, yes?

Am I right in the assumption that the main issue is that
./devtools/gen-avr-lib-tree.sh is called only when bootstrapping? I
guess it might be possible to (re-)do this at configure time. It
means the script needs to be delivered into the final release tarball,
but that's going to be the least problem.
I would (obviously) much prefer that the library can be built on at
least a few recent/stable versions of GCC (say, 4.8 through 5.1), as
opposed to just a single (matching) version.

Never trust an operating system you don't have sources for. ;-)
