this is fine for the current OCaml releases, but we (@mirage/core) should upstream a cleanup of OCaml's configure and signals_osdep.h ifdef chain so we don't have to specify linux-gnueabihf and sed -i -e in the OCaml distribution.

these files (Makefile.Linux.arm and m.arm.h) should not be needed, but fully generated by our execution of OCaml's configure.

This looks nice, but unfortunately is now outdated (now that solo5 0.7 and mirage 4 is out) -- maybe someone would like to rebase / rethink this "solo5 on 32 bit" work? /cc @TheLortex
