And I suppose what is most interesting to me, though I haven't (and

/usr/share.
Is the file not architecture dependent? Can this same file be used
by all machines, no matter the platform? This is what /usr/share is
for. Otherwise, if the file does have architecture dependent settings
in it, then it belongs in /usr/lib.
The magic and magic.mime files are common to all architectures.
The corresponding .mgc files are binaries, and parts of these are
stored as little-endian or big-endian depending on the arch (text
strings, and nulls, are the same). e.g. (ac30 is x86 (le),
bassman is ppc (be) - sorry about the wide/wrapped lines)

If upstream want to put all of these into the same directory, that's
fine by me.
