Gotcha... I thought you were referring to gcc's terminology
of "stages". There, anything higher thant stage 1 is
compiled by itself which obviously won't work cross.
What you call stage1 is sometimes (and in Elinos, too) called
a "bootstrap gcc".
However: u-boot should be compilable with such a bootstrap
gcc, as it should not be dependent on glibc. (It is
bad enogh for it to be so dependent on several Linux
headers, but that is a compromise to be able to reuse
code from Linux - we had that before).
