Add -fdeclspec to NXT_RUBY_CFLAGS for Clang, if it's available. Clang incorrectly reports 1 for __has_declspec_attribute(x) in some cases, such as MacOS or Cygwin. That causes ruby code to break. ruby added -fdeclspec to their CFLAGS in 2019 to workaround this bug, since it enables __declspec() and therefore, the compiler behavior matches what it reports. Since we don't know what are all the architectures that trigger the clang bug, let's add the flag for all of them (especially since it should be harmless). Add this workaround only at the time of configuring the ruby module. This way we don't clutter the global NXT_CFLAGS with an unnecessary flag.
