If we failed to exec a process after fork we were losing the output message when output sync was enabled. Fixed in Git. Thanks for the report.

If you run Make with --output-sync=target along with multiple jobs Make will not show the full error of the last command which errored. See here http://stackoverflow.com/questions/35848934/gnu-make-4-0-output-sync-taget-doesnt-show-the-final-error and here http://stackoverflow.com/questions/32164266/how-to-use-synchronization-in-makefile for a few examples of the situation (the first link is my question).

This makes it hard to use with Jenkins or something similar as when the build fails no one knows what command had caused the failure or the message from the command that had caused the failure.
