What is the need for this?

At a higher level the bug it blocks:
https://bugzilla.mozilla.org/show_bug.cgi?id=715397

More specifically, to be able to build with the 10.6 SDK and run the binary on 10.5.
See 
https://tbpl.mozilla.org/php/getParsedLog.php?id=8360973&tree=Try&full=1#error0 for an example of what this fix.

Wouldn't it be better to use MACOSX_DEPLOYMENT_TARGET?

That part is in bug 702158, and I guess it can be #ifdef DEBUG like there.

No, that is the OS version we are targeting, not the SDK we are using. In particular, using that would cause the build to fail in the current setup (10.5 MACOSX_DEPLOYMENT_TARGET and 10.5 SDK).

Maybe. I will try and let you know.
