Gumstix uboot build
building gumstix buildroot has been fun. :) The only problems for me were:
that the uboot includes are of the #include <linux/config.h> type. This caused the compiler to try to include the config.h from my ubuntu linux headers rather than those in the buildroot directory.
I had to do a mkdir -p ./build_arm_nofpu/root/etc/udev/rules.d/ in the buildroot directory or one of the install scripts would puke.
I'll file bugs as soon as I can figure out who maintains this. :P
