arm64/aarch64 build fixes for nettle7 and libid3tag

[dhomeier]

Separating the packages addressed in #952 out here.
libid3tag works as proposed with updated config.guess (tested on old 10.14 installation with fink 0.45 and dpkg 1.10.21 as well). Both are building as aarch64-apple-darwin... now.
nettle8 from ab0978d builds without further changes.

I think the nettle7 fix is likely the best option. I'll have to cherry pick it though cause I'm not going to test libid3tag. Hopefully I'll get it in today as I need to get python27 in today

LGTM

Seems, this isn't enough

/usr/bin/install -d -m 755 /opt/sw/src/fink.build/root-nettle7-3.5.1-3/opt/sw/share
/bin/mv /opt/sw/src/fink.build/root-nettle7-shlibs-3.5.1-3/opt/sw/share/info /opt/sw/src/fink.build/root-nettle7-3.5.1-3/opt/sw/share/
mv: rename /opt/sw/src/fink.build/root-nettle7-shlibs-3.5.1-3/opt/sw/share/info to /opt/sw/src/fink.build/root-nettle7-3.5.1-3/opt/sw/share/info: No such file or directory

seems a missing dep maybe? I'm looking into it.

  Documentation:     no

checking for makeinfo... not-found

need a BD on texinfo

Once tested I'll commit nettle7 with this patch and the BD addition

Ah, of course; same as for nettle8 (at least on Ventura, <= 12.x still has its own makeinfo, but better to use the same build everywhere).
