didn't correctly start background jobs anymore. Strange that nobody
was complaining...
Add a dummy target for `builtins' in the Makefile, to prevent it
from attempting to build this file by compiling builtins.c. :-/
traditional behaviour, and it violates Posix.2.
Fixes PR # bin/880: /bin/sh incorrectly parse...
Fixes also an earlier problem report about the shell not evaluating
loops correctly. (Not files via GNATS.)

When comparing my recent parser change against the ash in 1.1.5.1, i
found that a couple of other problems in the same area has been fixed
there, but not in 2.2. Semicolons and EOF do also delimit words...
The && and || tokens do also terminate a command, not only the
newline.
While i was at it, disabled trace code by default, it served no good
purpose since it required the use of a debugger anyway to be turned
on. Instead, placed a hint in the Makefile on how to turn it on.
This makes the shell ~ 10 % faster and ~ 4 KB smaller. :)

This should fix it (passed my test cases). Originally discovered with
perl's Configure (well, in FreeBSD, I don't know how the NetBSD folks
discovered it).
