seems to work.  i tested with:

automake.git$ sudo cp lib/am/dejagnu.am /usr/share/automake-1.15/am/dejagnu.am

gdb.git$ cd sim && automake-1.15

build$ cd sim && make site.exp
/bin/sh ./config.status --recheck
...
configure: creating ./config.status
 /bin/sh ./config.status
config.status: creating Makefile
... 
  GEN      site.exp

build/sim$ rm site.exp && make site.exp V=1
set -e; ( \
echo '## these variables are automatically generated by make ##'; \
echo '# Do not edit here.  If you wish to override these values'; \
echo '# edit the last section'; \
echo 'set srcdir "../../../sim"'; \
echo "set objdir \"`pwd`\""; \
echo 'set build_alias "x86_64-pc-linux-gnu"'; \
echo 'set build_triplet x86_64-pc-linux-gnu'; \
echo 'set host_alias "x86_64-pc-linux-gnu"'; \
echo 'set host_triplet x86_64-pc-linux-gnu'; \
echo 'set target_alias "mn10300-elf"'; \
echo 'set target_triplet mn10300-unknown-elf'; \
list='site-sim-config.exp'; \
for f in $list; do \
  echo "## Begin content included from file $f.  Do not modify. ##"; \
  cat `test -f "$f" || echo '../../../sim/'`$f; \
  echo "## End content included from file $f. ##"; \
done; \
echo "## End of auto-generated content; you can edit from here. ##"; \
if test -f site.exp; then \
  sed -e '1,/^## End of auto-generated content.*##/d' site.exp; \
fi; \
) >site.tmp; \
rm -f site.bak; \
test ! -f site.exp || mv site.exp site.bak; \
mv site.tmp site.exp
