Your libgcc.a uses hardware floating point, whereas your u-boot (why is
it called armboot here...?) uses software FP.
Software floating point is a bad construction site in gcc toolchains;
you should use a toolchain which uses software FP by default. Dan
Kegel's crosstool generates nice ones that are known to work.
