Infinite make rebuilds

[Daniel Aleksandersen]

autoreconf -i
./configure
make -B

Expected: rebuild everything once regardless of freshness (forced rebuild).

Actual: rebuilds all the things forever in a loop. Non-forced make works fine.

This broke recently. Tested with most recent versions of Ubuntu, macOS, and Fedora.

Version e10c5e5.

I can reproduce the issue running gmake -B with GNU Make 4.2.1.

The build goes into an infinite loop running configure.

I've run autoreconf -i && ./configure && gmake -B with versions as old as 1.6.0 and still see gmake -B loop in the configure script. I think this might be something in autoconf that prevents you from running make with -B.
