[Buildroot] linux .config : override: reassigning to symbol AEABI

Hello all,

This morning I did a complete compilation from a fresh install. I get something working with OABI support (did not test EABI) but using an initramfs only. Once the kernel has booted the nfs mounts are working normally.
I think I will continue like this because it's OK with my needs.

It looks like there are some kind of cache effects in the buildroot configuration files  when the config files have modified several times, even if make flush or even make clean are executed. Did someone of you had such problem? In this case, what is the better option: starting from a fresh install or something else?

Concerning my first problem I can do further tests if you want so that we  get a better idea of what is going on; I did some tests without being able to get a better idea of the problem. See below.

Hello Peter, 
Thanks for helping.

My buildroot is configured with softfloat: 
$ grep SOFT .config
grep FPU .config
# BR2_FPU_SUFFIX is not set

And the kernel config : 
.../linux$ grep FP .config
# CONFIG_FPE_NWFPE_XP is not set
# CONFIG_VFP is not set

Mark : 
I have activated the DEBUG options in the buildroot and in the kernel config files. However, I do not get more debugging messages; I did append "user_debug=255 or 31" at the end of the kernel command line. Results are identical as what I described on Wednesday : 
* if I pass nfs_root options + init=/bin/sh to the kernel command line, I get a kernel panic,
* if I pass nothing more that the nfs_root options to the kernel command line, the kernel hangs after freeing the init memory.

Please find attached my buildroot, kernel and uclibc config files for a complete overview of my config

Thanks all for your kind help,
