[kaffe] configure shows error messages

[Ito Kazumitsu]

Today's configure shows the following two messages.

./configure: line 27350: test: no: integer expression expected
./configure: line 53725: test: =: unary operator expected

I forced configure to pass by changing

        if test x"$ac_cv_gnu_library_version" != x"no" -a "$ac_cv_gnu_library_version" -le "2002"; then
           ...
	fi

to

        if test x"$ac_cv_gnu_library_version" != x"no"; then
	if "$ac_cv_gnu_library_version" -le "2002"; then
	    ...
	fi
	fi

and

        if test $ac_cv_lib_gmp_mpz_get_d = no; then
                if test $ac_cv_lib_gmp___gmpz_get_d = no; then

to

        if test "$ac_cv_lib_gmp_mpz_get_d" = no; then
                if test "$ac_cv_lib_gmp___gmpz_get_d" = no; then
