The mktokens script fails when /tmp isn't writable (e.g., when building
in a sandbox with a different TMPDIR). Replace absolute references to
/tmp to relative references to TMPDIR. If TMPDIR is unset or null,
default to /tmp.
The mkbuiltins script was already hardened to work relative to TMPDIR,
also defaulting to /tmp.
v2 ensures that TMPDIR is quoted.
v3 adds an extra quotation that prevents extra pathname expansions.

Instead of detecting EOF using the input layer, I'm going to
use the parser instead. In either case, we always have to read
ahead in order to complete the parsing of the previous node.
Therefore we always know whether there is more to come, except
in the case where we see a newline/semicolon or similar.
For the purposes of sh -c, this should be sufficient.
