This seems like the wrong fix for whatever bug you're encountering. I
just built with NO_CURL and:

    $ ./t5561-http-backend.sh
    1..0 # SKIP skipping test, git built without http support
    $ ./t5562-http-backend-content-length.sh
    ok 1 - setup
    ok 2 - setup, compression related
    ok 3 - fetch plain
    ok 4 - fetch plain truncated
    ok 5 - fetch plain empty
    ok 6 - fetch gzipped
    ok 7 - fetch gzipped truncated
    ok 8 - fetch gzipped empty
    ok 9 - push plain
    ok 10 - push plain truncated
    ok 11 - push plain empty
    ok 12 - push gzipped
    ok 13 - push gzipped truncated
    ok 14 - push gzipped empty
    ok 15 - CONTENT_LENGTH overflow ssite_t
    ok 16 - empty CONTENT_LENGTH
    # passed all 16 test(s)
    1..16

So all these test pass.

Of courses I still have curl on my system, but I don't see the curl(1)
utility used in the test, and my git at this point can't operate on
https?:// URLs, so what error are you getting? Can you paste the test
output with -x -v?

If we do end up needing this after all it seems better to do something
like:

Not really a problem with your patch, we have lots of this copy/pasting
all over the place already. I.e. stuff like:

    if test -n "$X"
    then
    	skip_all="$Y"
    	test_done
    fi

or:

    if ! test_have_prereq "$X"
    then
    	skip_all="$Y"
    	test_done
    fi

Maybe we should make more use of test_lazy_prereq and factor all that
into a new helper like:

    test_have_prereq_or_skip_all "$X" "$Y"

Which could be put at the top of these various tests...
