The key is to generate the targets (foo|
from the source names (foo|bar.pod), and then have the pseudo-target
all depend on those generated targets as below.

-------------- SNIP -----------------------
.SUFFIXES       : .pod .man

PODSRC!=echo *.pod
MANPAGES=$(PODSRC:S/.pod$/.man/)        : 
                echo transform $< to $@

all             : $(MANPAGES)
-------------- SNIP -----------------------

Your requirement is slightly more complex because you
want a variety of suffixes (corresponding to man page sections).
So you'll want to find a way to deal with that requirement
using some kind of further substitution, probably a second step
that renames to .X
