Can you provide other details; in particular, are you running with
parallel builds enabled?  What commandline did you use to invoke make?
Is this reproducible?

Also, what compiler did you use to build make?  Do you have any extra
patches, etc. applied beyond basic 3.79.1?

These aren't as useful as they could be, since they don't have
linenumbers, etc. and I don't have access to the same binaries and
systems you're using.

Can you attach to these using GDB and/or to versions of GNU make with
debugging compiled in, and get stack traces there containing line
numbers, etc.?

I suppose one thing you might try, based on this stack trace, is editing
config.h and changing this line:

  /* #undef vfork */

to this:

  #define vfork fork
