Maybe, maybe not.

No. U-Boot does NOT use libgcc.a.

It is your compiler which requires libgcc.a.

Right. It has nothing to do with glibc. It's the  compiler  libraries
which  use  hardware  FP, which does not mix with any other code that
uses soft-float.

[This is why I have doubts if your  Linux  stuff  really  uses  soft-
float;  you'd  run  in  the  same  problem  there, too. But this is a
different issue.]
