Personally I'm mostly concerned about making it easy for new contributors to get a working dev system going on a super common platform without dealing with hard-to-diagnose errors, than people who actually want a different target as a deliberate choice. Do I understand correctly that there a period of time each year when major upgrades come out of sync and lots of people finish up running a toolchain and OS with this problem for a while due to the default target not matching? If so I wonder if other projects are running into this with AC_REPLACE_FUNCS and what they're doing. I suppose an alternative strategy would be to try to detect the mismatch and spit out a friendlier warning, if we decide we're not going to support such builds.
