Subject: [PATCH] Fix variable name in configure.ac.

$ac_cv_search_STRINGPREP_CHECK_VERSION should be
$ac_cv_search_stringprep_check_version, to match the first parameter of
the AC_SEARCH_LIBS([stringprep_check_version] above.

Running configure was giving a "test: =: unary operator expected" error.
