Hmmm... yeah, that could cause a bit of hassle for me, as well.

Checking a FreeBSD/i386 stable/9 /usr/obj as of r236226, I see 16544
files with permission 0600 and 710 files that have something else
(typically, 0644):

     710
d134(9.0-S)[7] find . -type f -name \*.o  -perm 0600 -ls | wc -l
   16544

So I won't claim "always mode 0600," but it looks like enough to be
annoying. :-}

I'm pretty sure I didn't change anything relevent from how I build with
gcc (on a different slice).

Peace,
