Yes there is a version of eubins that run up to 4% of sanity.ex that's the best I got up to now. It fail at the poke, peek test.
Who has built this one? http://openeuphoria.org/eubins/linux/4.1.0/arm-32-bit/eubin-arm-cortex-a8-2012-01-13-ee49c6b8a340.tar.gz This is the only one that load and run on my EfikaMX.
Jacques, the two eubins you referred to are two different abi's: hard and soft. We should really know what your system is and then work from there. With the 'hello.c' program you wrote, can you do the following on your EfikaMX:
gcc -v gcc hello.c -o hello readelf -A hello
This is just a quick test to check the abi settings of your native compiler.
Thanks,
Ira

What can I do from here?

P.S. no need to answer I found the softfloat compiler in rpi tools directory and launched a cross-compile with it.
Thanks Ira for pointing me in the right direction.
