Hello Christophe,
The issue is fixed by using ct-ng-linaro-1.13.1-4.8-2014.04 with "
--disable-multilib --with-system-zlib"
The exact command line of error has " -mfloat-abi=soft", even the gcc was
configured using " ct-ng linaro-arm-linux-gnueabihf"

Hello Joel
Could you provide us with:
- the exact command line used (the one calling GCC, with all the flags)
- the output of gcc -v the see how it was configured
From what you say it looks like your compiler is currently configured
to generated hard-float code by default, and that you are compiling a
module with -mfloat-abi=soft while the compiler has no support for
multilibs.
