Or it can be sed command as well:
KBUILD_VERSION=`sed -n '0,/^VERSION = [[0-9]]*/s,\
^VERSION = ,,p' ${KBUILD_DIR}/Makefile`

May be it would be better to pull this structure out:
if test -f "$KBUILD_DIR/Makefile"; then
KBUILD_VERSION=`sed -n '0,/^VERSION = [[0-9]]*/s,\
^VERSION = ,,p' ${KBUILD_DIR}/Makefile`
KBUILD_PATCHLEVEL=`sed -n '0,/^PATCHLEVEL = [[0-9]]*/s,\
^PATCHLEVEL = ,,p' ${KBUILD_DIR}/Makefile`
fi
AC_SUBST(KBUILD_VERSION)
AC_SUBST(KBUILD_PATCHLEVEL)
if [[ -n "$KBUILD_VERSION" -a -n "$KBUILD_PATCHLEVEL" ]]; then
WITH_MODULES="yes"
else
WITH_MODULES="no"
fi
Would appreciate any comment.
Thanks,
Alexey
