This issue has reappeared OS X 10.11 for make 4.1 built with NLS support when
executed under the fink package manager using the system perl. The cause
appears to be the indirect linkage of the CoreFoundation framework via libintl.
The CoreFoundation frameworks sources don't contain any EINTR handling for
interruptible system calls like read(), etc so there will be potential race
conditions for programs using fork()/exec() like make.
