Hello Masahiro Yamada,

Even the with this patch, we encountered a false error of generic board support. The problem was very interrmittent for us, but we were able to debug the problem to performing builds on EXT3 file systems which have a time stamp resolution of one second. To reproduce the problem, touch ./include/config/auto.conf and .config on a configured uboot tree on an EXT3 file system.

The patch below fixes the problem for us.

This makes an odd race condition problem I run into when doing massively paralell builds worse :( With MAKEALL no ARM boards build (ARCH wasn't set in time so it tried arch//Makefile for something) and buildman was also broken in a bunch of places.
