Hello Peter and thanks for the support.

Did exactly that from a clean svn. Incidentaly I notice that there are now 
far fewer activated defaults (no IPV6, CXX, locale, kernel compilation, 
etc...):
$ make menuconfig
$ make

Error 1

It also tries to compile gmp without the BR2_SOFT_FLOAT option. And same 
error with your .config.

Now gmp is a dependency of uclibc, right ? So I disable the FPU in there... 
same thing.

There's something wrong with the cross compiler, right ?!?
