I think there is a race and we need to adjust the packaging process for
libgcc/libc as I mentioned in the other email.

To reproduce I'm guessing something like:

"bitbake libgcc virtual/libc -c package -f" will consistently break
rootfs builds after that command is run.

(This relies on the fact that libc will take much longer than libgcc to
package.)
