[Buildroot] [git commit] package/nettle: add missing dependency on host-m4

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=d4ca1b03c0d6f34d10d10cab06ca28c24a7d296d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

nettle uses m4 during its build process. Without it, the build fails
with:

m4 ./m4-utils.m4 ./asm.m4 config.m4 machine.m4 aes-decrypt-internal.asm >aes-decrypt-internal.s
/bin/sh: 1: m4: not found

For the target package this is not visible, as the existing gmp
dependency pulls in host-m4. But technically speaking, nettle needs
host-m4 directly, so it makes sense to have this dependency.

For the host package, it clearly fails to build, but probably isn't
very visible as most systems have m4 installed system-wide: this was
noticed when building inside Buildroot's minimal Docker
container. There are no recorded autobuilder failures for this issue.
