Hi Tom and Masahiro,
Neither my collegue nor I could reproduce the problem you encountered with our patch and the build line, "LANG=C make -j8 CROSS_COMPILE=arm-linux-gnueabi- ph1_ld4_defconfig all". Any suggestions on other ways to fix the false error and not break paralell builds would be extremely appreciated.
Thanks,
Matthew Gerlach

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.
Me too.
Although I do not know why, Methew's patch makes it worse. Without MAKEALL or buildman, I hit the same error every time.
