I forgot to say:
I already use such a toolchain and only a few minor patch fixups were
necessary for arm-v7a-* (but it is clearly much more work to ensure that
it still works on every possible platform you support instead of one or
two)

Maybe it's also time to remove the glibc-ports entry as the major
architectures are included in glibc mainline since 2.19, right?

I'd also suggest adding --enable-stackguard-randomization to the glibc
default configure arguments.
Without it, every binary built with -fstack-protector uses the same
canary value (0xff0a0000).
With that option, the binary uses a different random canary at runtime
(different at each invocation, taken from /dev/urandom).
Debian and ArchLinux both have this option enabled since many years.

Cheers,
Clemens
