Apparently make evaluates its rules by passing them to sh.

Sounds like the ol' setpgrp() bug one more time (yeah!).  This bug
crept in in 18.53, and crept back out again in 18.54.  Apply the
following patch from the diff-18.53-18.54 file:
--------
diff -rc2N dist-18.53/src/emacs.c dist-18.54/src/emacs.c
*** dist-18.53/src/emacs.c	Sat Feb 18 09:03:50 1989
--- dist-18.54/src/emacs.c	Mon Mar 13 16:41:29 1989
