We also need to think about upholding support in GCC for
ARMv4(t) for the foreseeable future if there is a big web of
random deeply embedded systems out there that will need
updates.

But we should definitely preserve at least what we have.

Plain ARMv4 (and earlier) support in gcc is already marked
'deprecated' and will likely be gone in gcc-8 (it's still there as of
last week). ARMv4T is going to be around for a while, and you can
even keep building for ARMv4 using "-march=armv4t -marm" when linking
with 'ld --fix-v4bx'.

I think that we shall start complaining on the gcc-devel mailing list
now.

I would be hard to wake up in 2 years time and realise that we don't
have a modern compiler.

What distro or build system are you using? It would also be helpful
to test whether the -march=armv4t/--fix-v4bx workaround produces
working binaries for you, in that case you could report to the gcc
developers that the removal of armv4 can continue but that
the --fix-v4bx option in ld needs to stay around.
