Here's a quick, completely untested stab. Please backup your tree
before using it, any data loss is completely yours to handle. Esp.
you might want to omit the 'rm' at the end for testing.
#! /bin/sh
set -e
LC_ALL=C
export LC_ALL
adds=adds.$$
inits=inits.$$
tmp=tmp.$$
for file in `find . -name Makefile.am`; do
sed -n 's/^\([a-zA-Z_][a-zA-Z_0-9]*\) *+=.*/\1/p' "$file" | sort -u > $adds
sed -n 's/^\([a-zA-Z_][a-zA-Z_0-9]*\) *=.*/\1/p' "$file" | sort -u > $inits
needed=`join -v 1 $adds $inits`
mv "$file" $tmp
{ echo "$needed" | sed 's/$/ =/'; cat $tmp; } > "$file"
done
rm $tmp $adds $inits
Cheers,
Ralf
