Why don't we use a script like this:

set -e 
src=$1
dst=$2
shift 2

test -f $dst && tail -1 $dst | sed 's,/\* \(.*\) \*/,\1,' | md5sum -c &&
touch $dst && exit 0
echo "$@"
"$@"
echo "/* $(md5sum $src) */" >> $dst

Then just call it with:
	<script> <src> <dst> <build command>

This is much simpler and also it also gets rid of these small checksum
files.
