No you need a 4.8 cross compiler to build a 4.8 "native" compiler.  So you
should build a 4.8 cross compiler which will include all the target libraries
and then you do a 4.8 Canadian cross (you just need to do "make all-host &&
make install-host" as you already have all the libraries done by the normal
cross).
