liblzma: Update a comment. 

The C standards don't allow an empty translation unit which can be
avoided by declaring something, without exporting any symbols.

When I committed f644473a21 I had
a feeling that some specific toolchain somewhere didn't like
empty object files (assembler or maybe "ar" complained) but
I cannot find anything to confirm this now. Quite likely I
remembered nonsense. I leave this here as a note to my future self. :-)
