Thanks for reporting this bug!

After a quick analysis, it sounds like the AT91Bootstrap makefile is not parallel-build capable: it runs the "clean" procedure and the build procedure in parallel, so depending on the scheduling and other conditions, it may happen that some .o files get removed after they have been produced.

Can you try the below change and see if it fixes the problem for you:

diff --git a/boot/at91bootstrap/at91bootstrap.mk b/boot/at91bootstrap/at91bootstrap.mk
index d8caed7..35f6260 100644

The patch proposed in comment #2 has been applied with commit 3ebb2e80844088de6ea8a923762ac2c47437d810 in buildroot 2013.08.
Therefore I'm closing this bug.
