Yes.  'configure' tries shells in the order /bin/sh, /bin/bash,
/bin/ksh.  It does not test for $(...) support.  Still, it prefers
shells that support shell functions, so I am surprised it picked a
shell that lacks $(...) when ksh was available.

Does /bin/sh support shell functions on your host?  If so, we can fix
the problem by changing Autoconf to also prefer shells that support
$(...).
