Didn't work on Solaris 7.  I applied your series on top of master with the
change you described.  Here's the diff:

diff --git a/test-terminal.c b/test-terminal.c
index f4d6a71..6408a7d 100644
--- a/test-terminal.c
+++ b/test-terminal.c
@@ -6,7 +6,7 @@ static void newtty(int *master, int *slave)
        int fd;
        const char *term;
 
-       fd = posix_openpt(O_RDWR|O_NOCTTY);
+       fd = open("/dev/ptmx", O_RDWR|O_NOCTTY);
        if (fd == -1 || grantpt(fd) || unlockpt(fd) || !(term = ptsname(fd)))
                die_errno("Could not allocate a new pseudo-terminal");
        *master = fd;


Here's the result of the terminal test:

  # ./test-terminal sh -c "test -t 1"
  # echo $?
  1


And here's the output of t7006-pager:
*** t7006-pager.sh ***
*   ok 1: set up terminal for tests
* no usable terminal, so skipping some tests
*   ok 2: setup
* skip 3: some commands use a pager
* skip 4: some commands do not use a pager
*   ok 5: no pager when stdout is a pipe
*   ok 6: no pager when stdout is a regular file
* skip 7: git --paginate rev-list uses a pager
*   ok 8: no pager even with --paginate when stdout is a pipe
* skip 9: no pager with --no-pager
*   ok 10: tests can detect color
*   ok 11: no color when stdout is a regular file

* skip 15: default pager is used by default

* skip 17: core.pager overrides PAGER
* skip 18: GIT_PAGER overrides core.pager
* passed all 18 test(s)
