Here's the results:
 - Run OE busybox on working BR system
   Works

 - Run OE busybox with OE libc.so on working BR system
   Works

 - Run OE busybox with OE libc.so / libm.so on working BR system
   Works

 - Replace BR libc.so with OE libc.so
   Works

 - Replace BR libc.so / libm.so with OE libc.so / libm.so
   Works

 - Replace BR ld-uClibc.so with OE ld-uClibc.so
init[1]: segfault at 00000008 pc 2aaabc84 sp 7ff80f30 ecr 24

 - Replace OE ld-uClibc.so with BR ld-uClibc.so
   Works


So the ld-uClibc.so build by OE is definitely the culprit, and replacing it 
with the ld-uClibc.so from Atmel's buildroot makes everything better.


I'm going to investigate what possible differences could exist between the OE 
ld-uClibc.so and the BR ld-uClibc.so now.
