Let's do this. They are ancient (gcc 4.3, very old uClibc, etc.). They
were kind of useful in that they forced us to test a very old gcc, very
old uClibc, very old binutils, but I agree they have a lot of quirks,
and I'm not sure they are really actively used by our users.

Should we instead try to have some ancient ARM toolchain, in order to
keep testing old gcc, old binutils, etc. ? But even the ct-ng
toolchains that are quite old are causing a number of problems, and
have autobuilder exceptions.

Best regards,

Thomas
