Upgrade to GNU Make 4.3

Unfortunately this release is incompatible with Mingw-w64, and probably
Windows generally. Despite detecting fcntl() (i.e. HAVE_FCNTL_H == 1),
it re-defines its own, incompatible fcntl() and constants, so the build
fails. Even with the shim disabled, the program assumes the incompatible
interface and fails to build.
