[U-Boot] Bug in buildman?

["Andreas Bießmann" <andreas.devel@googlemail.com>]

Hi Simon,

while test-building 2015.01-rc4 I encountered following strange
behaviour of buildman:

--->8---

buildman complains about missing linker script for most boards which is
an error when building all avr32 boards. While it detects the correct
warning for still not fixed kwbimage.c maybe-uninitialized when building
just the single board which had an error before. Both builds are based
on v2015.01-rc4 and built in different locations.

Best regards
