I don't know an elegant solution, but I can give you the script I use.

There is another glitch if you have a big code base with many 
sub-...-subdirectories: merlin look for the .merlin in the current 
directory and the parent directory. So you need to copy or link the 
.merlin in many directories. And then the directories inside the .merlin 
must be absolute. Moreover you can't put the .merlin in every 
subdirectories (ex: .svn, tests,...).

For frama-c I added this Makefile target:

.PHONY:merlin
merlin:
#create Merlin file
         find `echo "src cil external" | xargs -n 1 -d ' ' readlink -f` 
\( -name .svn -name tests -o -name doc -o -name result -o -name -o -name 
oracle -o -name "*.cache" \) -prune -o \( -type d -printf "B %p\nS %p\n" 
  \) > .merlin
         echo $(OCAMLGRAPH_MERLIN) >> .merlin
         echo "PKG zarith" >> .merlin
#create link in subdirectories to the merlin file
         find `echo "src cil external" | xargs -n 1 -d ' ' readlink -f` 
\( -name tests -o -name doc -o -name result -o -name -o -name oracle -o 
-name "*.cache" \) -prune -o \( -type d -exec ln -fs $$PWD/.merlin 
\{\}/.merlin \;  \)
