 From the best that I can tell, Fedora 16 and newer are all broken.  (And I 
checked OE-Core, and it's also missing the second part of the fix.  I should be 
sending a patch for that soon.)

Fedora Bug filed: https://bugzilla.redhat.com/show_bug.cgi?id=975597

If necessary we can relax the check I added by removing the 'space' on the 
makefile_test.a: ... line.

Obviously it hasn't been failing for the oe-core (and likely meta-oe) builds. 
But it is still broken.
