Comment (by cypherpunks):

 The applied patch misses quotes around the variables. This causes
 `configure` to report test errors such as `test: too many arguments` (and
 curiously does not terminate the configuration process). The attached
 patch adds the quotes.

 Regarding the applied patch, the
 [https://www.gnu.org/software/autoconf/manual/autoconf.html#index-
 AC_005fSEARCH_005fLIBS-344 autoconf manual] states
 >The result of this test is cached in the ac_cv_search_function variable
 as ‘none required’ if function is already available, as ‘no’ if no library
 containing function was found, otherwise as the -llibrary option that
 needs to be prepended to LIBS.

 There is no test whether the variables contain 'no'.
