[tex-k] portability of format dumps

Hi Norbert,

In theory, as Akira said, .fmt/etc files from web2c are and have been
100% portable across platforms, independent of endian-ness, Windows
vs. Unix-ness, and everything else.  (I seem to recall that being one of
the first changes I made to web2c back in the mid/late-80s.)

There was a bug a few years ago, possibly present for more than one
year, where the format files were endian-dependent.  That was never
intentionally the case.  

(I wish we would reliably test this every year against the bug coming
back, but there are rarely enough minutes to get it done.)
