Indeed, it seems that the problem is more with the test framework
than with the 'dircolors' program. When I create a file named 'owt'
with

$ cat owt
TERM none
owt 40;33

then (in an interactive bash):

$ ./src/dircolors -b owt
LS_COLORS='';
export LS_COLORS

$ (unset TERM; ./src/dircolors -b owt)
LS_COLORS='tw=40;33:';
export LS_COLORS

When I add an 'echo as_unset=$as_unset' statement to tests/envvar-check,
it prints
  as_unset=unset
at each test run.

Concentrating on a single test run:
$ make check-TESTS TESTS=tests/misc/dircolors

When I add a line 'print "<<<$ENV{TERM}>>>\n" to tests/misc/dircolors.pl
and run the test, the file tests/misc/dircolors.log contains
  <<<dumb>>>
So, somewhere the empty value for TERM must be replaced with the
value 'dumb'. Since build-aux/test-driver does not do anything with TERM,
my guess is that perl is the culprit. The perl version is 5.22.2.

When I add a line
  $ENV{TERM} = '';
near the beginning of tests/misc/dircolors.log, then the test succeeds.
