Peter Eisentraut e752727195 Make Unicode makefile parallel-safe
Fix the rules so that each rule is parallel safe, using the same
trickery that we use elsewhere in the tree for rules that produce more
than one output file.  Refactor the whole makefile so that there is
less repetition.

# Define a rule to create the map files from downloaded text input
# files using a script. Arguments:
#
# 1: encoding name used in output files (lower case)
# 2: script name
# 3: input text files
# 4: argument to pass to script (optional)
#
# We also collect all the input and output files in variables to
# define the build and clean rules below.
#
# Note that while each script call produces two output files, to be
# parallel-make safe we need to split this into two rules. (See for
# example gram.y for more explanation.)
