it looks target OS version detection in ./configure fails. (10.7 <= ver < 10.10)

macOS's AvailabilityMacros.h does not contain macros for future versions.
a version number to compare with "MAC_OS_X_VERSION_MIN_REQUIRED" should be a numeric literal, not a macro.

• MAC_OS_X_VERSION_10_7 => 1070
• MAC_OS_X_VERSION_10_10 => 101000

dln.c has same issue.

$ sw_vers -productVersion
10.9.5
$ uname -r 
13.4.0
$ cat conftest.c 
/* end confdefs.h.  */

            #include <AvailabilityMacros.h>
int
main ()
{
static int test_array [1 - 2 * !(MAC_OS_X_VERSION_MIN_REQUIRED >= MAC_OS_X_VERSION_10_7 &&
                 MAC_OS_X_VERSION_MIN_REQUIRED < MAC_OS_X_VERSION_10_10)];
test_array [0] = 0;
return test_array [0];

  ;
  return 0;
}
$ cc -c conftest.c 
conftest.c:8:50: error: use of undeclared identifier 'MAC_OS_X_VERSION_10_10'

[Bug #18879] Fix macOS version detections

macOS's AvailabilityMacros.h does not contain macros for future
versions. If a version macro is not defined, consider only earlier
versions to be targeted.
