[clang] regression: tmpfs is not mounted from fstab

[Boris Samorodov]

Hi!

I can't mount tmpfs from fstab if world/kernel are build by clang,
however just making world with gcc works fine. The last revision I've
tested:
-----
% uname -a
FreeBSD h30.sp.ipt.ru 9.0-CURRENT FreeBSD 9.0-CURRENT #1 r219024: Fri Feb 25 13:17:07 MSK 2011     bsam at h30.sp.ipt.ru:/usr/obj/usr/src/sys/BB  i386
-----

The previos clang kernel at r218879 works. Mounting from rc.conf
works as well.
