Something change in my environment, or something, because I can't
build pg_filedump anymore, although it hasn't had any recent new
commits:

pg_config
/bin/sh: line 1: mkdir: command not found

Looks like something messed with PATH, but I don't think it was me. In
any case, very little has changed in the patch since I last built
pg_filedump successfully, so I won't worry yet.

I pushed with a couple cosmetic adjustments:

- Removed no-longer-needed #includes from configure checks
- Added a comment that we deliberately don't guard on __has_attribute
- switch things around to use #ifdef instead of #ifndef for clarity

Thanks Andrew, for picking this up again!
