I have a slightly different opinion. This only solves one problem which
is due to FORTIFY_SOURCES on ubuntu native gcc. On newer host distributions (with
gcc 4.x). When we chose a OE distro (target) which uses old compilers (
3.4 or below) we end up compiling the cross compilers with relatively
newer compiler which may have problems. Same could be true for other
host utilities which are old. 

I think best solution is to build a native compiler from the same
version first. Now it will add to compilation time but
then we can have ASSUME_PROVIDED.
