remove support for 4.06 and 4.07

hannesm commented 4 years ago

as discussed in https://github.com/mirage/ocaml-freestanding/pull/65#issuecomment-558767805, drop support for OCaml 4.06 and 4.07 series. The reasoning behind this is manyfold:

MirageOS 3.7 series requires at least 4.07.0
as MirageOS team, we agreed once upon a time to support "the latest two major versions of OCaml"
since OCaml 4.08.0, autoconf is used, which we use (since #65) to great success
no longer checked-in autogenerated files

also, 4.11 will be branched soon, and in other projects I am raising the lower bound to 4.08 (https://github.com/mirage/mirage-crypto/pull/51).

@hannesm freebsd with 4.10.0 still seems to be failing with some unclear error (looks like the job got killed?). Ok to merge this as-is?

hannesm commented 4 years ago

to me this is fine to merge, I just clicked on restart for the FreeBSD 4.10 VM.

Merged, but I see a transient failure on Travis processing the merge commit. Ignoring it, but for the record:
