detection in configure script

---------------------+---------------------------
 This new port is failing to build on Big Sur, as the configure script is
 failing to detect the two-arg version of gettimeofday().

 Example configure output, from the ARM builder:

 {{{
 [...]
 checking if gettimeofday takes tz argument... no
 [...]
 }}}

 With the result being a later compilation error, due to attempted use of
 gettimeofday() with a single argument.

 11_arm64-builder/builds/31657/steps/install-port/logs/stdio

 Still reviewing `configure.ac` from later upstream releases, to see what
 I'm missing.
