make: skip shell -e option when running commands

POSIX says, regarding execution of commands:

   The execution line shall then be executed by a shell as if it
   were passed as the argument to the system() interface, except
   that if errors are not being ignored then the shell -e option
   shall also be in effect.

As a non-POSIX extension, skip the use of the -e option.  This is
how GNU make and BSD make behave.
