I know it isn't a good thing to have many copy-and-pasted contents
(set file descriptions etc) in all MD files, but it's much more annoying
to maintain a bunch of .if \n [${MACHINE}] conditionals for all ports
and maintainers rarely notice that they also have to prepare or update
MD contents in MI content file with messy ifdefs.
XXX: of course common text should be shared by mdoc macro etc.
but I doubt playing mdoc(7) is really worth...
* The merged contents file didn't work out, so nuke it and put it back
into each port directory. Most still have the now-pointless conditionals;
these now should be deleted.
* fix alpha, amiga, and arm32 to delete the maze of twisty little conditionals
