I hope soon, but I can't say yet, and I'm not the one deciding this.
In my opinion, it's only fair that the people who paid for the work
get the opportunity to implement and use it for some time before
other people do.

I think this would be a good thing in any case. If people are aware
of the EABI, it is hopefully easier for a non-Debian Developer like me
to get armel patches merged.
[ One thing I would like to ask is if people submit/apply patches that
add 'armel' to the debian/control Architecture: line, to add 'armeb'
to there as well. I submitted patches to add 'armeb' to a bunch of
packages in the sarge days, but a number of those patches never got
applied, and a lot of new packages have only 'arm' and not 'armeb'. ]

OK, so -gnu it is, then? Guillem, do you agree?
This is what I have now:
thecus1:~# dpkg-architecture
DEB_BUILD_ARCH=armel
DEB_BUILD_ARCH_OS=linux
DEB_BUILD_ARCH_CPU=armel
DEB_BUILD_GNU_CPU=arm
DEB_BUILD_GNU_SYSTEM=linux-gnu
DEB_BUILD_GNU_TYPE=arm-linux-gnu
DEB_HOST_ARCH=armel
DEB_HOST_ARCH_OS=linux
DEB_HOST_ARCH_CPU=armel
DEB_HOST_GNU_CPU=arm
DEB_HOST_GNU_SYSTEM=linux-gnu
DEB_HOST_GNU_TYPE=arm-linux-gnu
thecus1:~#
Does it still need an ABI tag, or can we just special-case 'armel' in
the rules files for binutils, gcc and glibc?

Right. There's also a bunch of packages that assume that they need
__attribute__((packed)) on all ARM systems, which is no longer always
true with EABI, and there's also a bunch of packages that still assume
FPA word order even if defined(__VFP_FP__). These will need patching
for EABI in any case. I have patches for a number of them.
