As far as generating the line, the patch is OK,
but it seems to me that this command should make
the script stop unconditionnally
(with a zero exit status if the test succeeded and non zero otherwise).
One way to achieve the desired behavior could be to run the
line in a sub-shell (enclosing the line between parenthesis):

(make check 2>&1 | tee gmp-check-log>>  $TEST_LOG 2>&1&&

Another way could be to eliminate any piping to tee during the tests
(testing the input line for '| tee'), since
the output is recorded anyway in $TEST_LOG...
I'd prefer this solution, otherwise we'd have to change how tests
are handled on a case by case basis each time the book adds
this kind of command (which was only in glibc when jhalfs was written)
