[Buildroot] static libgcc_s

Hi Ulf,
Yes: you are right I can compile U-Boot with NOSOFTFLOAT=yes with the "default" toolchain (i.e. the one with shared gcc enabled), but I cannot compile AT91 bootstrap for that I have (following Eric's tip) a static-only toolchain that compiles bootstrap.

So for now: two toolchains. 

Thank you all for help

I removed the -msoftfloat from the 
cpu/arm920t/config.mk and

After this I have a single toolchain which allows me to build:

* dataflashboot.bin (for AT91RM9200)
* U-Boot
* Linux
* Root File System

It does not allow me to build at91-bootstrap.
