This patch removes native_only, and removes code disabling various 
components (not in gcc or src) on various hosts or targets, on the basis 
you give that if you put such a component in tree you want it to be built 
(which I think applies even for any that are kept as build components).  
OK to commit?

Remark: disabling "newlib" (as opposed to target-newlib) for a host seems 
odd, as does disabling "libffi".  So maybe the code disabling directories 
for host can be simplified even more.
