I've reproduced this error on my machine at work, where I previously 
worked out the right stuff to put into ~/.buildman.

Now that I try the regular build process (in-tree build using just make) 
multiple times after a "git clean -f -d -x" , I see the same error that 
way too, sometimes, so it's nothing to do with buildman.

However, I don't always get the error with either plain make or with 
buildman, and it doesn't always complain about the same file:

This isn't anything to do with these patches; I can see the exact same 
issue building the following existing boards in unmodified u-boot/master:

rpi (arm1176, no SPL)
tnetv107x_evm_defconfigs (arm1176 no SPL)
mx35pdk_defconfig (arm1136, no SPL)
nhk8815_defconfig (arm926ejs, no SPL)
imx27lite_defconfig (arm926ejs, SPL)
vexpress_ca15_tc2_defconfig (ARMv7, no SPL)

Strangely I don't see the issue for:

seaboard (ARMv7, SPL)
maxbcm_defconfig (ARMv7, SPL)

I wonder if bisecting would show up where this issue was introduced.
