Merge #17703: build: Improve configure.ac formatting
3ab18246254019896132d1cdb8af2dcdb213ec3b build: Use dnl for all comments in configure.ac, rather than # (fanquake)
8ddcbb4e41fa91e7f80efe6d9c4d5e9bb1355036 build: Remove backticks from configure.ac (fanquake)
Pull request description:
Use `dnl` for all comments, rather than `#`.
Remove backticks - Their usage for the `bdb_prefix` and `qt5_prefix` commands may have improved backwards compatibility in some cases, however we now require recent versions of macOS. I'm not sure why they were being used in the `HAVE_STD__SYSTEM` and `HAVE_WSYSTEM` defines.
