I tried this:

$ MACHINE=qemux86 bitbake-whatchanged nativesdk-perl
Figuring out the STAMPS_DIR ...
Generating the new stamps ... (need several minutes)
ERROR occurred!
Traceback (most recent call last):
  File "/media/build1/poky/scripts/bitbake-whatchanged", line 342, in <module>
    sys.exit(main())
  File "/media/build1/poky/scripts/bitbake-whatchanged", line 303, in main
    old_recon = recon_dict(old_dict)
  File "/media/build1/poky/scripts/bitbake-whatchanged", line 96, in recon_dict
    if os.stat(full_path_pre).st_mtime > os.stat(full_path_cur).st_mtime:
OSError: [Errno 2] No such file or directory: '/media/build1/poky/build/tmp/stamps/armv7a-vfp-neon-poky-linux-gnueabi/bash-4.2-r4.do_compile.sigdata.80ff8a0bb7180f101517f35e8cf4ba8b'


and it looks like the environment isn't preserved since this is
defaulting to beagleboard which is what is in my local.conf, not the
MACHINE=qemux86 I expected.

Cheers,

Richard
