grep 2.5.3 does not build if makeinfo is not present

[hbent]

Hi again,

grep 2.5.3 does not build if you don't have makeinfo installed.  The
configure script does not appear to check for it at all, and it is run
unconditionally:

Making all in doc
gmake[2]: Entering directory `/usr/share/src/grep-2.5.3/doc'
restore=: && backupdir=".am$$" && \
am__cwd=`pwd` && cd . && \
rm -rf $backupdir && mkdir $backupdir && \
if (makeinfo --version) >/dev/null 2>&1; then \
  for f in grep.info grep.info-[0-9] grep.info-[0-9][0-9] grep.i[0-9]
grep.i[0-9][0-9]; do \
    if test -f $f; then mv $f $backupdir; restore=mv; else :; fi; \
  done; \
else :; fi && \
cd "$am__cwd"; \
if makeinfo   -I . \
 -o grep.info grep.texi; \
then \
  rc=0; \
  cd .; \
else \
  rc=$?; \
  cd . && \
  $restore $backupdir/* `echo "./grep.info" | sed 's|[^/]*$||'`; \
fi; \
rm -rf $backupdir; exit $rc
/bin/ksh: makeinfo:  not found
