we hit the same problem in the Blackfin kernel 
(.init.text / .init.text.1 / .init.text.2) and it was for this reason ... one 
section incorrectly lacked "ax" flags unlike all the others

if you have scanelf installed, you can run:
scanelf -k .init.text.1
and usually this will find you the builtin.o file which will narrow down the 
directory of objects, one of which needs fixing.  just look at the flags in 
`readelf -S`.
