Hello, freebsd-current.

  I have -CURRENT i386 installation which runs r245741 now.
  Default compiler is clang:

> cc --version
FreeBSD clang version 3.2 (tags/RELEASE_32/final 170710) 20121221
Target: i386-unknown-freebsd10.0
Thread model: posix

  This system is used to build NanoBSD images (and ports for these
images) for my home router, which has AMD Geode CPU:

Geode(TM) Integrated Processor by AMD PCS (499.91-MHz 586-class CPU)

 Build system has only one setting in /etc/src.conf and


  NanoBSD image build includes many options, and "CPUTYPE=geode" is
among them.

  Today I've rebuilt all ports (including samba36) and image (from
 r247117). And new samba port (samba36-3.6.12) failed to start on
 target system (with Geode CPU). It gets "SIGILL" (!!!).

  I was able to get core file by running "testparam" in NFS-mounted
 R/W file system, but after that GDB (on build system, as NanoBSD
 image doesn't contain one) says, that it could not access memory at
 failure address to show disassembly:
