Building asterisk - undefined reference to `__sync_fetch_and_add_4'

Hi

I was wondering if anyone else is having this problem building
asterisk on -CURRENT.  The problem may not be with FreeBSD - it
looks like gnu configure is incorrectly detecting the CPU as "i386"
when it's actually a pentium3:

configure: Package configured for: 
configure: OS type  : freebsd7.0
configure: Host CPU : i386
===>  Building for asterisk-1.4.11

The i386 doesn't have any atomic primatives or something like that
(maybe just according to gcc-4.2).  If I frob the configured sources
and change the i386 to pentium3, then the build works, but I don't
have enough asterisk foo at this point to verify that it actually
works.
