Fix build failure on macOS with --enable-shared
./spec/ruby/optional/capi/ext/array_spec.c can match with spec/%/ if
using GNU Make under version 3.81. make command installed on macOS is
3.81, so ruby can't be built with default make on macOS with
--enable-shared option since https://github.com/ruby/ruby/commit/bda56a03a625793cb3fd110458c3f7323d73705e
