Build all Flex files standalone
The proposed Meson build system will need a way to ignore certaingenerated files in order to coexist with the autoconf build system,and C files generated by Flex which are #include'd into .y files makethis more difficult. In similar vein to72b1e3a, arrange for all FlexC files to compile to their own .o targets.Reviewed by Andres FreundDiscussion:https://www.postgresql.org/message-id/20220810171935.7k5zgnjwqzalzmtm%40awork3.anarazel.deDiscussion:https://www.postgresql.org/message-id/CAFBsxsF8Gc2StS3haXofshHCzqNMRXiSxvQEYGwnFsTmsdwNeg@mail.gmail.com
