The solution was a simple "rm -rf toolchain_build_powerpc" when compiling
from buildroot.
But I still have NFS woes, a bit off-topic for the busybox mailing list, so
I'll crosspost to buildroot at uclibc.org, I hope it's OK.
Briefly put: I can't mount mount my root filesystem off NFS and I can't
event do a normal mount.
/etc/exports on the host contains:
/home/guinevere/prj/buildroot/project_build_powerpc/genepy/root
*(rw,async,no_all_squash,no_root_squash)
(note that some of the path is a "ln -s", don't know if it can be a problem)
I can mount it fine on a different PC with this in the /etc/fstab:
192.168.1.185:/home/guinevere/prj/buildroot/project_build_powerpc/genepy/root
/media/loop nfs wsize=1024,rsize=1024,hard,intr,rw 0 0
When I try to mount it on my target board:
$ mount /media/loop
[ 922.797996] rpcbind: server localhost not responding, timed out
[ 922.853581] RPC: failed to contact local rpcbind server (errno 5).
[ 957.926565] rpcbind: server localhost not responding, timed out
[ 957.982067] RPC: failed to contact local rpcbind server (errno 5).
[ 993.055133] rpcbind: server localhost not responding, timed out
[ 993.110661] RPC: failed to contact local rpcbind server (errno 5).
mount: mounting
192.168.1.185:/home/guinevere/prj/buildroot/project_build_powerpc/genepy/root
on /media/
loop failed: Input/output error
And in the meanwhile I see this in the log of my host:
Apr 15 12:40:58 lpsc6185x mountd[6261]: authenticated mount request from
192.168.1.200:804 for

(/home/guinevere/Min_UartLite_NetLite_Ace/buildroot/project_build_powerpc/genepy/root)
I've enabled every RPC related stuff in buildroot/kernel (I don't know if
all are necessary):
$ egrep "RPC|NFS" `find -name .config`
