The issue comes from everything after "norm" being treated like a
normal-mode command so that's "Join, delete the first two characters,
space (go forward one character), pipe (go to column 0), space (go
forward one character), u (undo), p (paste), dat (delete around a
tag), e (go to the end of a word).

You have a couple options. To use the method you were using, I'd
recommend

:set hidden
:argdo g/^`define/norm JXX

then, after checking that they're all like what you want, issue

:wall

There are a number of other alternatives but this is what I would
have done as it's a bit more robust in the event of weird spacing
between the "define" and whatever comes after.

:argdo %s/^`define\>\zs\s*\\\n\s*/ /|up

-tim
