Well that's strange yes.

Meanwhile, I made some progress on this bug (even if I have no time...). 
It seems that the problem comes from brk.o, as using the one generated 
with 4.0.2-6 in the tree built with 4.0.2-5 reproduces the problem. The 
reverse is also true, ie copying brk.o built with 4.0.2-5 to the tree 
built with 4.0.2-6 fixes the problem.
