Subject: [PATCH] configure: require GNU make 3.82

Reportedly make 3.81 already fails since commit:
b04be559ddf4a7f0a5cdc0b9abc2bcfc4aae25cc "gbuild: implement static
partial build"

<sberg> mst___, the `/usr/bin/make --version` "GNU Make 3.81" I have on macOS does not work to build LO (Some LinkTarget.mk:913 erroneous endef error is the first I encounter)

There was an ESC decision years ago to drop support for make 3.81.
