Details:

The macro ENULLLOOP in make.h does not work as expected to be fixed in
bug#2846.
If "_c" returns zero with errno=EINTR when called first, the inner while-loop
repeats calling "_c", but without setting errno=0 before the next call.
So errno keeps being EINTR, while "_c" already succeeds, and make run into an
endless loop.
