Sure it is.

I just wanted to make sure that I understood corretcly.
Since my user applications seems to run fine under linux I assume that my glibc 
supports softfloat.
U-Boot does not use glibc but libgcc.a. Since the compiler complains while 
compiling U-Boot, it seems that my libgcc.a does not support softfloat.
So the problems lies in how my compiler was built and not how the glibc was built.
Did I get this right?

Thanks a million!
